It's possible that people commonly conflate their feelings towards Mono with their feelings about the general CLR/C# environment. Not saying that's definitely the case here, but how many web-targeted projects exist for .NET/Mono? Obviously, there's ASP/MVC - but what else? Compared to the number of web frameworks/etc for Java? (I don't know.) The anti-Microsoft sentiment seems strong among web devs. So, when new devs start out, they might read a lot about how if it comes from Microsoft - it can't be good. I am fairly certain that that is a strongly contributing factor to people's avoidance of it.
