Welcome! Best way to get acquainted is to browse and observe for a bit. Fluther has a particular culture, and we try to sustain it because that’s the comfort zone for both the old-timers and the newer members who’ve found us congenial.
The number of “lurve” points by someone’s name gives some indication of how long they’ve been around. You can also look at their profile and see when they joined and how they present themselves. Lurve comes mostly from being awarded “great answers” (GAs) and “great questions” (GQs) by other users—“jellies,” we call them.
“General” questions expect serious answers, on topic. “Social” can be humorous and have humorous responses. “Meta” questions are about the site. You might want to try us out with one of your “silly” questions to see how it goes. Put it in Social.
This used to be a very active, lively site with lots of members. Now it’s small, with about a hundred active participants and quite a few others who drop in and out. There’s no further development coming; the founders and maintainers moved on years ago, and one of them, out of the goodness of his heart, just keeps us from crashing. So WYSIWYG.
This recent thread might give you a feel for the Fluther community. We do have our eccentrics, but in general we’re a pretty agreeable lot, allowing for idiosyncrasies, and we have wonderful, loyal, attentive moderators who protect the common welfare.
Not to speak for others, but I think probably Fluther IS our weird fetish.
