Given a lot of the comments, it seems like the poor guy is getting a lot of crap from people who don't get why someone would write something like this. I wonder how projects grow in that community with that level of resistance at their origin.
They don't, generally. C#/.NET hasn't exactly been a fertile breeding ground for innovative new open source projects. The most important .NET project are typically Java or Ruby ports (unit testing ports, Rails-alikes, ORM ports, NAnt, etc.).
A lot? Most of the comments seem positive or inquiring in nature. I think it's a good idea that people weigh the pros and cons, especially when it's not obvious why they should select this framework over any other.
