I would say from my own personal experience that when I first came to Fluther it seemed very restrictive, and I was reprimanded for being too “lax” or “childish” in my questions and answers, because I thought that Fluther was just like any other Q&A forum.
But damn was I wrong….
Now I LOVE Fluther for its restrictions, because I think that it offers people a special forum for “higher-minded” and “intellectual” questions and answers. It is an amazing place to get good (meaning not idiotic) responses from people who actually know what they are talking about. With this said, I also think that Fluther can be a great place to get quick esoteric answers, even if they are not geared towards the intellectual.
So to answer your question, I think that a lot of people have come to Fluther expecting it to be a lax and care-free forum where you can write whatever you want, however your want (like I previously did), only to find the contrary. But I love Fluther for this very reason, so go ahead and “drop out” if you can’t appreciate the specific awesomeness that is Fluther.
