I've ended up using neither tags nor "topic" folders (besides few folders in toolbar): for retrieval I rely on titles (names) and URLs alone. Every time I bookmark something I evaluate its title and URL, look for missing terms my future self could use, and then either reword the title or add raw "tags" in the end. Extraordinary bookmarks I supply with several * proportionally its extraordinarity (and make sure names contains no such sequence).

It serves me well: using native bookmarks search accelerator [1] in url bar * , keywords and 'rating system' allows me to for example quickly pull "best personal blogs of people writing about javascript":

    * *** javascript guru

I understand your worries, IIRC there used to be bookmark "description" field that was just recently removed (I've used it maybe twice) and if tags are globally used like this description was, your concern could be quite relevant. If need arises, perhaps some sqlite-fu could transfer tags to titles, at least.
