Yeah, though the implementation sucked. The interface to add to tag bundles couldn't really cope with my number of tags. I actually don't tag that excessively, I don't think. I basically tag for fandom, characters, pairing, length, genre (au, crossover, actionadventure, mystery, h/c, romance, angst etc.), major tropes (amnesia, amtdi, timetravel etc), kinks and sometimes pov-character and time period or location if they stand out. Quite frequently I run into the problem that I still undertagged, because on story finder comms someone asks for something that I vaguely recall I have read, but I haven't tagged for the particular thing they are asking for.
