Link: LinkedIn: Home.
I learned about LinkedIn in this very witty and engaging presentation. LinkedIn was referenced in the aforementioned talk, and I hadn't heard of it before. So I signed for an account, took a peek around the site which promotes networking, and promptly forgot about it until one of my educational technology cohorts added me to his list of "connections". While I am not sure what I have to gain by participating in this social networking site for adults, it is sort of cool in a six degrees of separation way. Since I've have had a few spare moments, I've gone through my address book and sent invites to be connected to all sorts of friends, colleagues and acquaintances. It's not spam, just me sending out info on something that might be potentially cool. So see you in LinkedIn hopefully!
Oh, and a colleague often makes comments about my networking... and while I think he's being complimentary, I don't really particularly relish the idea of accruing a long list of contacts. I simply enjoy collaborating and talking with others in my field so that I can learn from other's wisdom! The internet certainly has made this easier.
