Today I've seen some people hammering stacks of MSDN cd's onto the heads of some other people who obviously talk about what their employer wants to hear, f.e. Matt Puccini and others.
Have you people ever participated in some slashdot threads? If you have, you should know the phrase: "Don't feed the trolls!'. Simply don't answer obvious FUD by below-the-belt-pub-talk like "[insert todays trolls name here] is a moron" or other phrases which do good on birthday parties but are definitely not what .NET or its community needs.
Every technology has its pro's and its con's. For one, Java's library is very well designed, and much more open for extension with your code than .NET ('sealed' anyone? A pattern perhaps?). Talking about the aspects of the technology, that's what's worth the effort. Throwing mud onto people who make a living out of crying fool about 'the opposite's tool' however is not.
Feed your audience with knowledge they can build on and work with, not with bickering about how a pencel-king succeeded in upsetting some people at the other side of the fence.
