A little, but slowly. I've found that it's sharpened my rhetoric and allowed me to cut a lot of the dead wood away from my arguments. I've also had a lot of people share some fascinating essays with me regarding a host of topics. While not necessarily changing my viewpoint it has allowed me to flesh out some of the weaker points in my own personal philosophy. This forum, while often ridiculous, does have a lot of informed posters willing to share with you. Some are conservative, some liberal, some Libertarian, and some are socialists, and they're all useful to talk to. I happen to be a Libertarian, so I can find flaw and agreement with just about anybody. But the constant exchange of ideas has, in my opinion, allowed me to grow and evolve as a politically active individual. I'm definitely better informed, even if I don't always use the facts as other people think they should be. There's never been a lighting flash, "Eureka!"-style change, but this forum is one of the tools I've used to mature my thought processes.
