If it helps, for context, read this article: http://www.lhotka.net/weblog/WhySilverlightIsTheFuture.aspx and then maybe my takeaways #1-4 will make better sense after you see what kind of opinions are normal in .NET land.
Maybe your intent was not to openly hate .Net, but it's what you ended up doing. Your entire post was just comparing .Net to Ruby and saying that Ruby is better. It comes off as a bad sales pitch. Even in your update, you're still saying that .Net developers should try Rails. If you think that .Net developers are too isolated and close-minded, the solution is not to desperately pitch Ruby as some cure-all. There are a million ways to develop software that involve neither .Net nor Ruby, and you didn't mention any of them.
On an unrelated note, your blog logo doesn't work for me. It shows up broken. Just FYI.
