Don't think that .info sites are treated as spam in google,a number of high ranking good sites are .info sites.So don't bother about it.On SEO point of view there is nothing in .com or .org or .info.
I came to know that meta-search engines are better than normal search engines.But I couldn't figure out why?Do you have any idea about meta-search engines ?Which meta-search engine are you using ?
