- Are you a member of any online communities?
- Are any of these social networks appealing to you?
- What did you find that was interesting and that you might use later?
As far as the communities that this Thing mentioned, I am a member of last.fm. I don't use it very often, though. I do tweet, but have very few friends signed up to see my tweets. I am a political news junkie, so in the past I have been a member of and contributor to specialized political blogs. Netflix has a social networking component now, where you can have "friends" who can see your queue and share movie recommendations, so I have a few friends on there.
I looked at the list of social networking sites on wikipedia, and wow! I had no idea there were that many. I really liked the food ones, I had never even heard of those before. I am always looking for new recipes so I might use those in the future.
As with all these other web 2.0 things, I think they're only good in moderation. I just don't have the time to go signing up for every niche social networking site that might interest me.
