From those great guys who gave you Blogger, Ev Williams, Biz Stone, et al, we have Twitter, a way to find out what other people you like are doing.
Other people you like, other people like you, other people who like you and other people who may not like you much at all. But they are all nosy enough to wonder what you're up to. (And isn't everyone?)
It simply asks the question, "What are you doing?" and the answers are a tumble of text messages on a wide range of subjects.
And they are short ... like tiny little blog posts. Very short, 140 characters only.
And you get them on your phone or mobile device ... and this is the big thing. And oddly, Americans seem to be the last ones invited to the party ... that is the text and SMS party, so we're all excited about it, but it's been old news in Asia and Europe for a while.
But everything is going to that platform and high time. And as for start-up efforts and NextBigThings, I think it's the only interesting place to go ... mobile platforms ... except for maybe biotech stuff, but we are still too early with that.
