I thought the old system of separate tags for each worked pretty well, TBH - sometimes you want to find a recent Wally post, sometimes you just want to read some Flash stories. Being able to search either for Babs posts in general or only for Oracle stories gave an extra layer of precision to things. And if we'd actually been disciplined about it, it would have been cool to be able to look for stories about Bruce Wayne, as opposed to stories about Batman (since a tale where he never suits up has a very different feel than one where he's out rooftopping).
