Use for Twitter?

Well I'm not sure this qualifies as an important use for Twitter, but it certainly keeps me following it. I used to work at the University the of Houston and I follow a librarian who works there now. Twice in the past two months they have been sent home (or maybe one time they were NOT allowed to go home) because of tropical storms. For some reason these single sentence Twitter postings really transport me back to Houston and the scariest weather I have ever experienced.
