Teoma seems is becoming a real player now. The fact that they're making deals and being mentioned so often indicates to me that they will soon start getting more traffic. That's how Google started - remember?
I'm not crazy about the results but they're okay. I think people will always want alternatives - sometimes Google doesn't work for me, or I want to see another opinion, and Teoma may very well become one of those "second opinions", until maybe one day they become a real contender?
