When I commute home on the T (that's the subway in Boston, for the non-locals) I'll often twitter up a storm from my crackberry.  Last night I posted a tweet with a line from a Jay-Z song, just because I was in a spunky mood.

What surprised me is that I got a number of responses from people I did not expect, sort of like Twitter helped me find other Jay-Z fans.

• "Jay-Z Baby....He is coming out with Blueprint 3 Produced by Kanye and Timberland...Should be Hot" from HappyHourBoston
• "Great lyric, I used to set that as my away message on AIM." from Dan Abdinoor
• "Did not peg you as a Jay-Z fan... nice!" from Seph250
