@hiiiiiiii I think what you are seeing is that most people here, if not all, prefer fluther and find Y!A to be a waste of time. That doesn’t mean you should find Y!A a waste of time, but it does suggest that you are looking for something different than the average flutherite is looking for.
As many other answerers have said, fluther provides much more of a sense of community; you can say things in an adult way and acutally discuss topics instead of just answering questions. Because of the way fluther is moderated (i.e., by people, not bots), we get nuanced moderation that helps build the place instead of formulaic moderation that kills community.
All that having been said, your own opinion should be the one that counts for you. It really shouldn’t matter what anyone else thinks. So, when you ask a question like this, it suggests you are looking to create trouble, rather than asking a sincere question. A sincere question would be something like what are the pluses and minuses of Y!A. Or how do fluther and Y!A compare.
You asked a normative question. That is, you asked which is better. Questions like that create divisiveness. I’ll say it again. It doesn’t fucking matter which is better. There is no better. It’s only in your mind that one is better than the other! No one else is concerned with that question.
Now please, try to ask friendly questions, not divisive ones. You seem like an accidental troll who just made a mistake. Try to learn, and please don’t do it again.
Get it?
