Yes might be. I too face this sudden filter criteria getting autoset at times, just couldn't find a specific workflow so never reported. I am not sure how/where from they come! (contrary to yours where it can be assumed that silverlight was searched so used!)
Already used for articles. Would be quite nice in forum posts and such. There was some tool to copy code from the browser so that it didn't all get put on 1 line, but I forget what that is called. Would be very nice to just have that copy functionality for PRE blocks instead (would make answering questions easier).
Someone posted an answer to the question in question (so to speak), and the OP posted a followup comment to that answer as a new answer.
In my world, that seems wrong. Shouldn't he have posted the follow up question using the "Add comment" link for the supplied answer?
Or is he doing the right thing, and I'm wrong?
IF I'm right in my observation, maybe some clarification as to the button/link functionality is needed? Hey, even if I'm wrong, it seems like clarification is needed, because I might not be the only person puzzled by this.
