What startups here are focusing on developing on top of .NET?
kolosy: i was tempted to blog about this a while back. i've gone from java (back in the 'ole days), to c#/net only, to the view that platforms don't matter. or rather platform boundaries don't matter. i spent the last few months developing out a .net mvc framework for my dayjob. when it came time for us to build http://friendsell.com, that's what i and the guys knew best, so that's what we built on. but we wanted to use CouchDB as the backend... and so we did.there are subtle implications to the platform decisions you make, but on the scale of most startups, the extra $40 bucks a month you'll pay for that windows ec2 ami isn't gonna make a difference. what will make a difference is you building on top of the stack you're most proficient with. for us that meant building on .net and couch. for someone else that'll be RoR and mysql.
