I've considered it, but I'm kind of leaning towards no since the $100 fee doesn't seem worth it compared to how many units I'd probably sell. But we'll see!
Probably you could try to write to Best Indie Games - ClemmyGames. He covers new Steam releases. But you'll need to make some trailer for Steam release in this case. Also I think that it can increase player base of the game.
I'd highly recommend Northernlion on Youtube too, he has a Let's Look At series where he plays and discusses numerous games, mostly indie developed. He's got a great audience and he'd definitely love and recommend this cracking game :)
