Finding a colleague match only requires that you and another person worked at the same organization during the same time period. So, as tempting as it may be to make connection with people who worked in various appealing companies over the years, if you invent a work history in order to do that, you're going to Hell. Perhaps that is overstated, but if you falsify your employment history on LinkedIn in order to create colleague-links with people you haven't actually worked with, it's an abuse of the LinkedIn system and the trust of the LinkedIn community.

9) Play by the rules. There are a number of ways to misuse LinkedIn in such a way as to convey the message, "I don't care about the long-term health of this network or the company that built it - this is All About Me." Including your email address in your LinkedIn name, for instance, makes a fee-for-use service like InMail superfluous for someone who wants to reach you, which is (if nothing else) exceedingly rude, seein' as how LinkedIn provides the basic functionality to users at no charge. Unless you want to broadcast the message, "I don't care whether LinkedIn can optimize its revenue strategy or not - I'm gonna optimize my connect rate," you might consider rethinking your Me First approach.

10) Value relationships over transactions. As in physical-world networking, valuing people for their intrinsic worth over the business transactions they enable is key.

After a decade (and for some of us, longer) online, we know all about Netiquette, right? Don't use all caps in your subject line (or, God forbid, the body of an email message). Don't send attachments to people who don't know you well. Don't we know pretty much everything there is to know about etiquette online?

Well, maybe not. Online networking sites like LinkedIn can challenge our ideas about what constitutes white-lace-handkerchief behavior online. In fact, if we've learned that it's important to be polite when using email, it's even truer in the social networking sphere. Here are ten tips for establishing yourself as a well-mannered online networker, when using LinkedIn:

1) Create a user-friendly profile. Your LinkedIn profile is your virtual business card. Make sure that it represents you the way you want to be viewed by strangers - make that 'people you haven't been introduced to, yet.' A sketchy LinkedIn profile signals that your busy day doesn't allow you to fill in trivial details like what you're doing now, what you've done in the past, or any other useful information. Such an incomplete profile won't serve you as you network on LinkedIn, but it's impolite as well: its message is "I'm going to use this database to find people, but I won't bother to include enough information about myself to indicate how I might assist anyone else." Take a few moments to fill in the gaps.

2) Invite true friends - or at least, true acquaintances - to connect. Spam is spam, and you must have a minimal level of contact with a person before inviting him or her to connect with you on LinkedIn. A contact - a less-intrusive overture than an invitation to connect - is a good way to approach people with whom you have no relationship. LinkedIn users vary in their views on how well you must know someone before connecting to him or her, but it's inappropriate to send connection invitations to people who have never met you, heard of you, or had any inkling of your existence (unless they have indicated a desire to be approached by strangers). Think about it: if you found a person's phone number on a scrap of paper, you wouldn't feel that you had permission to phone him. Your possession of an email address doesn't give you license to contact an unacquainted LinkedIn user and suggest a connection - and it's this kind of overzealous outreach that gets users in trouble with LinkedIn, as well.

3) When you make a request, be clear about your intentions. You'll find your LinkedIn contacts generally happy to forward your requests if you approach them politely and are clear about your goals. In the physical world, if you asked a friend to introduce you to his friend because of a mutual interest in sailing, and then actually hit the friend-of-a-friend up for a loan, you'd be viewed as a sneak. It's no different online. If you're job-hunting, say so. If you're looking for investors, ditto. A wolf in sheep's clothing soon finds his messages sitting, unforwarded, while his LinkedIn contacts wonder whether he can be trusted.

4) Reciprocity is a wonderful thing, and gratitude is key. When possible, it's great to include in your LinkedIn outreach messages some suggestion that you're aware of your obligations as a requester. That could mean an offer to make a useful introduction for the person who's forwarding yours; or an offer to help in some other way; or just a heartfelt thank-you for the introduction you seek. It's disconcerting for your first-degree forwarder to receive a slew of requests from you in one day (and this is common when one of your first-degree contacts is more-highly-connected than others) with no acknowledgement at all of the favor you're asking. LinkedIn is no different from the 'real' world, in that sense: asking for an introduction is a favor, and it's nice to show gratitude for that.

5) Pass along requests promptly, or say why you won't. Membership in LinkedIn is a kind of agreement with the community that you intend to participate as an active node in a large and vibrant network. If people send you requests and they sit there, unforwarded and unresponded-to, for weeks, you're not only the weak link in the system. You're impeding someone else's business efforts, and giving no reason for your bottleneck behavior. If you can't forward on a request or move a communique forward, say so - and say why. LinkedIn provides a handy list of reasons for declining a request, plus an "other" option - use 'em.

6) Avoid the boilerplate text, if you can. Of course you can. Unless you're terribly afraid to strike out on your own with creative verbiage, please make an effort to put your own stamp on the standard invitation language that LinkedIn supplies. For instance, you could mention something impressive that you've heard about the person you're contacting, or bring an old friend up quickly up to date on your doings. Using the boilerplate text shows a certain want of effort - so, even if you stick with the standard language, why not add "sorry to use the boilerplate text, but I'm not much of a wordsmith"?

7) Don't abuse your network. Once you have cultivated a network, it's tempting to reach out to the gang anytime you have news or a need for assistance. And LinkedIn's functionality allows you to broadcast a note to your posse of contacts, by way of a Profile Update blast. Use these sparingly, not as a substitute for the Daily All About Me Newsletter. If you do, you may find yourself being un-connected from people who can't manage the high volume of what's-new-in-your-life mailings.

8) Don't invent history to acquire colleagues. LinkedIn allows you to find former workmates at any company that has employed you, without being connected to them otherwise. Finding a colleague match only requires that you and another person worked at the same organization during the same time period. So, as tempting as it may be to make connection with people who worked in various appealing companies over the years, if you invent a work history in order to do that, you're going to Hell. Perhaps that is overstated, but if you falsify your employment history on LinkedIn in order to create colleague-links with people you haven't actually worked with, it's an abuse of the LinkedIn system and the trust of the LinkedIn community.

No less than in middle school, 'users' are never welcome company for long. "Ka-ching" networking - the kind of outreach that signals "Say, you could make me a buck today" is unseemly and unfortunate. LinkedIn is a fabulous tool that enables connectors and influencers to help other people and achieve their own goals, too - and it's great when we keep those priorities in balance.

Happy networking!
