I've been playing with Twitter lately, and wanted to jot down a couple of quick thoughts.
First, I'm really enjoying how you get to know people on Twitter... "ambient intimacy" isn't it for me, it's more a "playful intimacy" or something similar. It's light, non-demanding, surprizing, fun... the best qualities of the social tech discoveries that (not too long ago) got called Web 2.0. Fun. Light...
Second, it's a great way to ... meet people? Connect with others who seem interested in the same things, topics, people and such. People who think you're interesting! Delightful.
Next, it's fun to see how people use it differently! Real time notes about conferences, bits of daily life, poetry, weirdness, etc.
Last, and props to danah boyd for the question, (originally tweeted as "what is authenticity in Twitter" or words to that effect) the notion, implicit in the activity, of self-promotion. Twitter is about telling people about you, which... does a bunch of stuff. It starts from the assumption that they want to hear it! I find that sort of refreshing, really. People want to hear my thoughts? And more, it sort of accepts the activity of self promotion as valid. Wow! And yet it is, it's crucial to our social success in many ways... of course it's valid.
