Why? The truth is, I learn by doing and by speaking with others who do. So I dabble with Twitter, Plurk, Pownce, Spoink, Rakawa, Tumblr, Utterli, Yammer, FriendFeed, 12seconds, and probably a few others that I signed up for and forgot to use. I have found a nice collection of people that I like to follow, and some people follow me too. So microblogging appeals to the extrovert in me, and I'm strangely fascinated reading what other people are doing (or what they say they are doing). Narcissism and voyeurism are at play.
