Pew Research Center has taken a look at Twitter and the numbers are encouraging for the micro-blogging service. As Britney Fitzgerald from the Huffington Post reports:

On the whole, users appear to be more actively participating in the online conversation, according to Pew’s data. While 4 percent of adults spent time on Twitter daily last year, now 8 percent log in on a regular basis. Among 18 to 24-year-olds, the tweets are flying out faster than ever; twenty percent of internet users in this age bracket tweet nearly everyday.

Other facts from the study: 28 percent of African Americans who are online are active in Twitter, and the majority of all users are female.
