Twitter Across Ethnicity and Dayparts

Simply wanted to share this post from the Awl, titled "What Were Black People Talking About on Twitter Last Night?"  The author notes the fact that he might get some flack for noting the trend - but I've certainly noticed the tendency of Twitter's trending topics to change in both subject and user base over the course of the day.  Last night around 8:30, for example, the top trending topics were #isitme and the Soul Train Awards, with a quick look at the posts indicating that the majority of people involved in the conversations were indeed black.  The Awl provides some stats, and asks the question:

...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?

At least worth a look.  And worth thinking - perhaps organizations looking to reach specific groups on Twitter - ethnic, racial, or otherwise - need to do quite a bit more research on their target audience's usage to effectively use the technology.
