what makes you read this?

For me it's how recent it is. I don't like posts that are a few weeks old. I wish they would be deleted actually so that this is kept current. I also don't like answering posts that are really dumb and in which the person obviously just asked to ask any sort of dumb question but that they don't really care about the answer. Such as "Whats your favourite colour?" I like posts that need more than a one line response.

Whatever grabs my interest is what I am attracted to. Also the more shocking the subject title is, the more bound I am to answering that discussion.
