Jason Levine points out that Sphere is even more splog-infested then Technorati. Plus even the non-splog results are very weak. No point in ever going back to Sphere, if this is the best they can do at launch then there is no reason to think it can rebound. The only good thing is that according to Om Malik (who was "impressed" with Sphere) they only spent $200k on their so far grade-Z search product.
