Is this the future of Twitter? Check out what Nascar is doing right now: https://twitter.com/hashtag/nascar
Twitter really did something nice by keeping to 140 characters. Everyone can use it, even race car drivers, and it works better on mobile than Facebook does for the most part. Damn, I wish Facebook would overhaul its iOS app.
Also, Twitter is ahead in its ability to gather things together thanks to Hashtags. Funny, wasn't it Chris Messina who invented those? Any irony to the fact that he now works on the Google+ team?
But Facebook is working on providing this stuff too. Its interest lists at https://www.facebook.com/addlist are far superior to lists over on Twitter.
