there are various domain extensions from .coms for companies to domain extensions for countries. but when it comes to a non-localized keyword (like shopping in the uk or something), does google favor domain extensions? like .com over .info? because since i've been working more and more, and since .infos are relatively cheap (for the first year's registration), i've been considering buying more and more of them.

so would it be a good idea to stick with .coms? or would building sites on .infos be a good idea... or not?
