I know it's an ancient topic, but I'll respond anyway just to clear something up.

Times have changed, online distribution has become much more attractive and easy, marketing can be done through Facebook, Twitter, Youtube, online game portals, game magazines that do feature indie games and what not, but then again that list is about 6 years old anyway, so what would you expect?

It makes sense that many games won't get any attention from the bigger publishers or even online game portals, because frankly many games really aren't worth it. Best bet for those is selling them yourself through your own website.
