It's like that on ever forum i've been on. I don't let it get to me.
If you want to answer then click on the thread and reply, if it upsets you then move on to the next
Personally, i'll skip over any thread with single word subjects, meaningless terms(what is... how do... help..., etc), or if the topic of the thread cannot be determined by the subject alone. Following this recipe has really cut down on the amount of noise I have to read through to get to meaningful content. Finally, if I can't make sense of the first two or three sentences, I skip the rest of the thread.
