Switching to different results pages (1-10 to 11-20, for example), the ajax is convenient but because you are contracting the old results and expanding the new ones at the same time. I would try doing one after the other (either expand the new results and then contract the old ones, or vice versa.)
The name sansj is not something that would stick in my memory, but I am curious to know what it means.
Bonus points for having Canada as a region, but I wonder why there is no US? Do you intend for "all world" to be mainly US?
The search results are a bit cluttered, you might want to think about what parts of the results are important to your users and stick the rest in a "more info" box (shown on mousover, perhaps) or something.
The results aren't quite as good as other search engines, but since it is community powered it should improve over time. A search for "blog hosting" revealed no relevant links in the "voted results", but most of the top 10 results were relevant. Did you build your own index, or do you use an API? If its your own index, I am impressed with the quality of results, considering you don't have the resources that the search giants do.
