Apparently, it's now possible to get a list of visible tags for a livejournal. Good news. I'm assuming the ugly formatting will eventually be cleaned up — part of it's the fault of the css stylesheet I cooked up for myself, which I can't edit due to my current inability to do anything other than web browsing, but part of it's the fact that LJ's s2 style system hasn't completely caught up to the availability of this new content.
