There are many great sources of security information, but lately it seems that more and more of the commentary deteriorates to something equivalent to this:
It's a dog!
No it's not!
Is too!
I like kittens.
You just don't understand how dogs work.
Maybe if we feed it dog food...
And so on.

I don't want to discourage anyone from following blogs, forums, or any other source of information- but if you don't add your own BS filter, you will get frustrated and miss some great information.
My approach to dealing with this is twofold:
First, whenever commenting, I try to add to the conversation in a meaningful way and include relevant information where appropriate.
Second, I tend to skim over the pointless posts and avoid "feeding the trolls".
I will admit that sometimes I fall short and add incite instead of insight, but I'm working on it.
