Yeah, I'm kinda flip-flopping on whether or not this would be a good addition to the free account level -- there are two things (this and comment editing) that I've been vaguely considering as potential free account features, but I really do want to hold off on making any changes to our account levels until paid accounts are more appealing. Search was a big'un, but there are so many LJ paid features that we just don't have that I'd like our paid accounts to be a bit more beefed up before we start turning some things free...
