I signed up for LinkedIn the other day on the recommendation of a friend. I don't know what to think just yet. I was finally able to get linked up with that friend - even though he was in the system, I was unable to find him when I searched. Then I sent him a connection email, which he thankfully accepted, and I was suddenly connected. So now what? I don't know.
Apparently the idea is that if I'm looking for something, I can search this trusted network that I'm building to see if I can find someone. Same with previous cow-orkers and the like. Thus far, it just seems like another service that I probably won't use.
The whole problem that I have with social networking of any kind, be it contacts or bookmarks, is that I rarely look for stuff in that way - though perhaps I'm just proving my age and should get with the program. We'll see how it turns out.
