As far as the name goes, I think Trickybeck came up with it.
The creation of the sandbox was partially my fault and that of the old AoK posters, though we never asked for it. There was a several thousand post-long thread in the FFXI main forum that was getting out of hand and was completely off topic. We asked for it to be nuked and moved the conversation to my journal, where it continued for about 33,000 or so posts until everyone either left the boards or migrated to this forum. The problem is that while this was going on, someone started up a "FFXI Off Topic" forum and Alla wasn't down with that idea. That quickly took the name Out of Topic, which was the old name of the Asylum, and this forum was named "Rants"... come to think of it, Tricky might have been the one to offer that name, in which case I'm not sure who would have picked the name "Asylum".
