A couple of days ago TechCrunch posted a screenshot of what was believed to be an early version of the new Wikiasari search engine that Jimmy Wales has been talking about. And it was blogged here on Smart Mobs.
But Wales is saying that the screenshot has nothing to do with the project, in a comment to that post and also on the Wikiasari page on Wikia (since taken down, but screenshot is here).
The Wikiasari page also now gives a bit about the background of the project, and Wikisearch is not mentioned. The project was originally called 3apes.
