Funny Where to Find Free games on Steam

This is the most off-the-wall-but-still-sane thread I've seen in a while. A poll with nothing to do with the topic, a somewhat introductory thread, and a question on where to find something all in one :hurr:

I'm pretty sure free is difficult to come by, but you can enter contests here that some people do every once in a while where users give Steam product keys. Granted, most of them are absolutely trash games but a few good games pop up now and then.
