I just had an insight about why Twitter is good.
Another friend of mine just started blogging, and as I subscribed to her blog in my blog reader, I was dismayed at the prospect of adding one more stream of information to the pile that I already don't have enough time to post comments on, or even read. I'm glad that we all have the means to publish our journals, our photos, our videos, but my ability to keep up with it all won't scale. I can't even find the time to read the national news most days.
But I do read headlines. And if I could get a daily digest of my friends' and colleagues' lives and insights, on a single page, 140 characters at a whack, I would read that religiously.
It shouldn't be an aggregate of their recently-published blog or photo titles; that wouldn't be the same thing. I don't want to read text that describes or refers to other content. I want exactly what Twitter asks for - "what are you doing?"
FriendFeed gets close, and I like the image thumbnails, but all the different kinds of information in one pile slows me down - e.g. I don't want to mentally filter out everyone's del.icio.us links while I'm looking for the meatier stuff.
I never thought I'd be advocating a Max-Headroom-style blipvert in the place of real content, yet here I am. I can't keep up with unlimited information. Sign on to Twitter and help me out?
