I'm (obviously) for sorting out the boards. The ones that I highlighted at the beginning were the main offenders that stuck out like an orange jumpsuit in the business district.
Since you're asking for opinions, I'd generally agree that most of them could be worth moving to the Social board (although I haven't thoroughly read through each page). I'd also have to agree with yunyun that "You know you're a RAFian" and "Things that remind you of RAF" are questionable. Some small aspect might stretch to make it feel like it's a Social topic but I would say "You know you're a ..." or "Things that remind you..." type topics are spammable and are better suited in Bored Board. In fact the Animorphs Boards have some similar topics but since the Animorphs equivalent topics are VERY closely tied to Animorphs I haven't suggested moving them.
Dino you are right to point out slippery slopes and precedents but I am not too concerned about this because I trust Richard's decisions. At the end of the day, he has successfully managed these forums for many years now and knows when to say no. There are many forums out there on the net that have died or don't have anywhere near the popularity or consistent following that RAF has.
