So far I've had great experiences with .tv's Google will always prefer .net and .com over others but when those are useless parked domains the .tv definitely has a chance to rank extremely high for its keywords
extensions MAKE NO DIFFERENCE! You just see more high ranked .com's because theres more out there. Don't let these noobs tell you otherwise.
To say Google would rank purely on a domain suffix suggests their algorithms must be crap. They're not.
If they call themselves SEO experts, then they don't know anything about the Internet then lol. It would be extensions-ist (racists?) for google to judge by what comes after the dot "." Google is too damn smart for that BS, theres a reason why google is the best!
No bias against .info But I hear that ICAAN is gonna make all TLDs possible i.e. you can have a .dp or .car or .anything that you can think of...
