I love playing indie games. I conduct my search on sites like Indiestatik which is a pretty good place to start. I even look for devs on twitter to get their sites and stay in touch with them to support their projects. Also, I try to search the steam store and browse around reading about games and watching trailers I stumble upon on youtube. It's also good to interact with local gaming communities. Gaming gossip also spreads like a wildfire.
I've posted some reviews and even bug tested some games. I've organised giveaways on my blog too. (I'm currently giving away PapersPlease by Lucas Pope n__n Here to enter).
