InsaneJournal Announcements

I plan on buying a permanent account, but I'd like to solicit an opinion, from Squeaky or anyone else with experience in this sort of field. I'm undecided on whether I ought to buy it for this journal, which maintains my PB icon/layout community, quibblercons, or for the community itself? Does anyone feel that one makes radically more sense than the other? I don't use this journal for anything other than icon-related stuffs, so it wouldn't particularly benefit me in terms of flists or texting or whatnot; mainly I just need to be able to test layouts to make sure they work correctly for people applying them to paid journals, perhaps post polls, and whenever I do close the journal I plan on opening it up to everyone, rather than shutting it down to everyone, so the option to make all entries not f-locked in a few clicks would be awesome.

Thanks to anyone who might weigh in! :)
