Twitter for 32
Twitter names for all 32 teams, stumbled on in the NFL.com game center pages while looking for something else entirely. I'm sure they're somewhere, maybe even here, I don't care. I love name spaces and a number of teams made interesting choices when picking their names for twitter. UpperLowerCase doesn't matter on twitter, essentially it's all lower case. A team can present it however it likes.
I think the NFCN discovered twitter late, or way too early. I'm not sure which but it made me laugh. The Vikings most of all (in order to be mobile they don't have a city, so they need to let you know that this is the football team).
