Programmer looking for co-founder/designer

I feel like I've seen a few out there already, but none of them jump to mind enough for me to refer you to.

I am a developer from Mumbai, India. I used to be a game programmer and I have worked on a published game. I still do some hobby game development here and there.

I have taken a liking to web development as well. I currently work full time at a web startup. This is something I want to do on the side for now. Although I have played around with PHP and Ruby, C# is currently the language of my choice and for web development I like working on the ASP.NET MVC framework.

I am interested in web projects. I have not really narrowed in on idea for the first project yet. I have a few ideas buzzing around my head. The one that I am currently prototyping is based on helping users find people to collaborate with (somewhat like some of the sites already mentioned in this thread). The other one revolves around meeting new people. More info available on request. I would perhaps prefer brainstorming an idea together. That way we both connect with the idea.

I have already looked at ProgrammerMeetDesigner.com and builditwith.me to find the kind of a guy I am looking for but haven't had success. Some suitable people that I found on there never responded back.

The reason I say this is because a good co-founder needs to be passionate about the problem. They need to be really interested in solving it to contribute meaningfully and come up with innovative solutions.
