Stef has been busy integrating the wikipedia and technorati APIs into his 'wikiproxied' vesion of bbc.co.uk/news

Next, I want him to build a feedback mechanism that allows users to correct erroneous wikified links, as well as suggest their own phrases & associated links.

User-suggested and rated phrases & links (and maybe scopes) be a great way of building up a social search engine, if you could get enough scale. .

Stef's also hopeing to do a toolbar which does similar chicanery for the whole web. This is harder than it looks, due to the wide range of browsers out there needing to be managed in different ways. Technorati have just had one done one for FireFox only.
