I've been on Twitter for about 20 months and tweeted 1000 times.

Using that ratio (50 updates/month), we can estimate that their 10,000 status updates cover 16 people over a year.

My first instinct was "why not?" but thinking about this more, that looks kind of thin. Of course, I'm assuming a lot of things away...

It sounds to me like the 10,000 "status updates" include only status updates containing the keywords, probably from the Facebook search function.
