Yes. It displays only those entries, which are present in both "sets", so to speak; it'll display only those entries, which have been assigned the tags. Ex.: I've got a tag "Linux" http://del.icio.us/a.skwar/Linux and a tag "howto" <http://del.icio.us/a.skwar/howto>. If I "plus them together", only those bookmarks are shown, which both the tags "Linux" *AND* "howto" -> http://del.icio.us/a.skwar/linux%2Bhowto I created a Yahoo! Pipe which allows to do just that. See <http://pipes.yahoo.com/pipes/pipe.info?_id=_qPh_TP02xG9PbWtjUnRlg>. You can of course also get a RSS feed :) Hm... It just occurs to me, that this pipe is pretty much useless, as del.icio.us already provides a feed for the combined tags. For example for "all" the "linux+howto" bookmarks at http://del.icio.us/tag/linux%2Bhowto it would be <http://del.icio.us/rss/tag/linux+howto>. > Are there any plans to add services which return the popular union of > more than one tag? What do you mean with "popular union"? Would you like to get a feed for "linux+howto" from the "Popular items tagged"? Kinda those popular linux http://del.icio.us/popular/linux tags, which also are shown in the popular howto list at <http://del.icio.us/popular/howto>? If so, that's yet another task for Pipes ;) Alexander Skwar -- Nothing in progression can rest on its original plan.
