Pool will be an Olympic sport just as soon as they let in darts, horseshoes, beer pong and cornhole. As lame as some (well, most) of the Olympic sports are, you're never going to see them include bar games. Now if someone decided to create the Barlympics...
Pool in the Olympics wouldn't help the game anyway, although I'm pretty sure this topic has been covered in about 62 other threads. Don't feel bad though. The darts guys feel just as pissy about their game being excluded from the Olympics too (at least they did in 2006). The article in The Guardian is actually pretty amusing, as you could remove the word "darts", replace it with "pool" and have the same argument that's been made over and over again.
