If you're seen deviating from the social norms, you will get push back, and it's seldom kind or constructive.
For example, I wrote this some time ago: http://dave.fayr.am/posts/2011-10-4-rubyists-already-use-mon...
I received a lot of hate for this post, both on this site and in other ruby circles.
When I wrote this post: http://dave.fayr.am/posts/2007-06-07-Multicore-And-Ruby.html I was banned from multiple ruby communities and called "the joe lieberman of ruby" by a prominent rubyist.
I don't mean to pick on the ruby community here specifically, these are just the oldest so it's least likely to re-open an old argument.
I could point to other examples. I'm considering going back to blogging myself, but my experience is that negative feedback overwhelms positive feedback 3:1.
