As of Sept'2011 it looks like no new spaces have been indexed since 2003.
- look at WikiSpaces
- for a custom widget that they don't have in their auto-list, you can just enter the HTML in as "Other HTML"
- I don't think the Del.icio.us API supports this anymore, likewise its Terms. Though I think the API docs aren't current/accurate.
Dec'2011: Jerry Michalski noted (in an Email List) how he'd like a real-time Auto-Complete to give him matching page names from his spaces once he kicked things off with the left-double-bracket (double brackets).
- he'd like that in all his apps (WebApp): GreaseMonkey?
- maybe pull pagenames from Sister Site-s, too? That encourages convergence of Wiki Name-s, as with Del.icio.us tags.
If this db includes a mod-date (hrm, not included in AllPages pages usually - may need to use RSS for this, too), then it can be a wiki-specific Meme Tracker: wikinames created/changed in many spaces in the past day.
