Straddling - good/bad/has its place?

[Kirkrrr]

This is something I've been wondering about for a while - does straddling have a place? If so, how would you use it? For a while, I thought it was just a waste of money (just raise 2xBB from UTG with 7,2o and you've accomplished the same purpose), but I've seen some good players do this, and it DOES change the dynamic of the game. What does everyone think about this?
