I don't really have a go-to place. Nowadays I find most people via twitter or just via randomly scrolling through the games over here.
Way back between 2008 and 2010 it was Tigsource, then Rock Paper Shotgun (which still is the only gaming site I visit on a daily basis). I also heard about a lot of games via Rock LeeSmile's Indie Impression series. Unfortunately he stopped doing those almost entirely.
I'm in a bit of weird spot right now, because I'm in the process of switching sides. I have a game that I want to release comercially next year and I'm still trying to come up with ways to convince people to take notice. Right now my strategy boils down to "make a Prototype, make a trailer and don't stop talking about this thing, until it's done". Which probably isn't the most elaborate way of doing things, but it should be a good start right?
