I'm fascinated by "social networking tools" (which I think is a stupid name for them, but whatever) and blogging stuff in general. Which is really weird, when I think about how highly I regard my own opinion (that being, not at all), and how frankly pointless I think putting it online at all is (which, now that I think about it, might be a major contributor to the demise of my anime blog/news site).
But still, I get drawn into Twitter (and Twitpic), upload occasional YouTube videos and had to stop myself from requesting a 12seconds account; as cool as the idea is, I can't see myself vblogging, really - not when I blog "properly" so infrequently. And that's without having to really identify myself to the wider internet. I was still more excited than I probably should have been when I discovered that I could post (and watch) YouTube videos from my phone, though.
I still enjoy seeing how The Internet (by which I mean, the people and entities connected to and via it) finds new ways to communicate with itself. On their own, individual Twitter posts are just pointless minutae (and in a lot of cases, seem rather narcissistic), but there's something interesting about how they form a single cohesive narrative over days and weeks and months in a way that self-contained blog and journal entries don't. There's a lot to be said for the minute-by-minute reactionary nature of Twitter too; it made watching the second Presidential debate much more interesting, for instance, to see hundreds of other people's reaction in real time as it progressed.
That sort of thing isn't maybe what the creators of Twitter had in mind when they started it, but I find it fascinating to see how The Internet has adapted to the application and how they've adapted the application itself for their own way of communication.
