I've put up a Disqus feed on my site! Even a guest can now comment on the weirdness that is called games.
In case you want to leave some quick feedback without any restriction for an account, you can now go straight there.
Also, I'm now participating in an collaboration project of the weirdest kind for Game Maker. The hoster called it PassaJolt. Every developer gets one day to work on the game and then passes the file to the next programmer. We have planned to do this two rounds and then see what happens. You can watch the buzz around PassaJolt on this forum topic on GameJolt. The game is already coming quickly along, but we still have a long way to go.
Also, passajolt is the best thing that has happened to my games, and the worst thing that has happened to my email. :P - bobmoo, GameJolt community
