There are more black people than white people on Twitter, and this is only recently becoming obvious to people because of new Twitter stuff like Trending Topics:

But seriously—talk about being in a bubble!—demographically, there is a greater proportion of black people than white people among the Internet-using population on Twitter: according to Pew, 26% of African-Americans online use Twitter; only 19% of white Internet people use Twitter. So really the question is: why does Twitter get so white and boring during the day? Don’t white people do anything at work?

So many data at play in this that I don’t want to say anything, but this is really interesting for what it says about Twitter’s power as a general communication medium with high availability outside the socioeconoomic ranks of affluent suburban office workers.
