Pogo is an excellent way to play online games and meet people from all over the world literally.  However, if you are not a paid member, the games you can play are limited and you have to deal with "advertisements" in the middle of your game.  Pogo also requires a good chunk of memory from your computer to work.

There are a great deal of good people playing on Pogo, but you have to remember there are alot of not so great people too.
