I only have one developed .info site but I don't see any penalty for .info. The search phrase "vestido de boda" (wedding dress in Spanish) produces 2.8 million results without quotes and 68K with quotes. Per Google Adwords keyword tool, the phrase is searched about 8 thousand times monthly (plural would be better). In either case my ministe with a few videos, pictures of my wife searching for dresses and minimal textual content is on page one of Google position eight (without quotes which is the way most people search) for that phrase. However, the page which appears is the privacy page which neither has the keyword phrase nor any content about wedding dresses? The only thing I can imagine is Google likes text and that is the one page with more text than any other :D
However, a comparable and higher-quality wedding dress minisite (in regards to videos and photos but Google doesn't care) on a .TV domain doesn't get the same favorable treatment. The phrase "vestidos de novia" shows far fewer results but our site is on page twelve of Google while a .COM minisite (another registrant, older site and more text) with the same keywords is on page two. It appears .TV does not get the same favorable treatment as .COM, .NET, .INFO by Google.
