Of course I have. I deem the comments/explanations by users such as Taxing Matters, KnowItAll, and few others enlightening and very helpful. That's what I mean by serious, not the fact that some use this to be "Judge for a day".
So why wouldn't we want a button for those that are helpful? Honestly not all their posts are serious either. And very few people are on here to play judge for a day. You give some of the most unhelpful advice of anyone on here from what I've read honestly.
