My opinion is that it's really where mapped roleplays go to advertise. There's some unmapped roleplays there too, but they(personally) aren't as interesting. I love that it is giant, however a lot of space is unused, and it feels like it was only half-finished, like most parts of FH. I don't do too much in Flourite, though, as I only go there to find mapped roleplay groups for my characters. For those who do most of their roleplaying in FP, the movie spam is just as bad as the General spam. You have to turn it off to read the last person's post, and for a little while I didn't know you could turn some chats off. Stone Bridge is one of the best places to hang around, though, as I made quite a few friends there.
Overall, FP isn't a bad place, but it's not perfect either. Movies spam, for new players, is a pain, and it just feels unfinished.
