Just created a swicki (search + wiki) social search engine, T.I.M. Search, using Eurekster's technology (beta). Check out the link to the right and the search box way at the bottom.
It uses preferred sites, site recommendations and key words (I included 170). In the future, it will add sponsored search.
Seems to work just fine. A search on the term 'tower' (not included in my 170) returned generally very relevant results. Pretty amazing. Is this the end of Google?
UPDATE: How about this for locking-in users?
