The Twitterverse is ablaze with talk about Netroots Nation, the convention of liberal bloggers and activists being held in Pittsburgh.
#Nn09, a hashtag that contains the abbreviation for Netroots Nation 2009, is a trending topic on Twitter. Trending topics indicate the most popular subjects of conversation on the microblogging site.
Former President Bill is scheduled to appear at Netroots Nation over the weekend, so look for elevated Twitter traffic then as well.
