The number of Twitter users who provide personal information in their bios has more than doubled since last year; 82% of Twitter users now provide a name, compared with only 33% in 2009. And 73% provide location information, compared to 44% in 2009. Forty five percent give a website address, up from 22% a year ago. This seems to indicate that Twitter users are becoming more comfortable disclosing personal information on the site, but more importantly perhaps, that having a profile on Twitter is becoming increasingly important.
