External search

A question I’m grappling with today involves listing items on other sites with tags used on Elgg. If you click on “metadata”, I ideally want to see not just other Elgg users who’ve been thinking about metadata, but also citations in other weblogs, on other websites, and in academic papers.

This is very doable. The question is, if I start adding more and more to the tag search page, is it going to become unmanageably long? Would it be better to have a link at the bottom saying “this tag on other sites”?

I’d quite like other people to do the same with Elgg-based services, so I’m also going to add RSS feeds for each tag.
