I finally got around to trying LinkedIn and I am impressed. Time will tell whether this is merely a novelty, or a bonafide business networking tool. LinkedIn is essentially an online social networking web site for professionals. You check your rolodex against the every other LinkedIn user, and all matches are linked. For example, let's say I have a contact named Napoleon and Napoleon is also on LinkedIn, we then would be shown as a link. The cool thing is, I can also see Napoleon's links and can contact them with his permission. The chain goes on and on, however, there are very strict controls on what info you can see and how far down the chain you can contact people. The privacy controls were designed so that even a Fortune 500 CEO would feel at ease using the application. When I signed up I was pleasantly surprised to find several folks from my rolodex already LinkedIn.
How is this useful you might ask--well, it in essence makes all your immediate contact's rolodexes transparent. For example, I could be looking for a someone who works in the plastics industry. Unbeknownst to me, my friend Bill who I golf with every week, has a good friend who works in plastics. That connection could be right there under my nose for years, and unless I asked I would never know about it. LinkedIn theoretically provides a solution. If Bill and his friend were also LinkedIn, I could easily check if anyone I know knows anyone who works in plastics, and find Bill's friend. Did that make sense?
The previous example brings up an important point. Unless LinkedIn gets a substantial critical mass of users, the solution is ineffective. Currently, the number of users is increasing almost exponentially. Provided that LinkedIn continues to provide a good service with the best privacy protection possible, this could be huge. In fact, it could change business "networking" forever. For now, I recommend the application. Get LinkedIn.
