.infos
Personally, I'm a big fan of .info potential growth. But, I think it will take a few years to catch on.
Theoretically, it could be a great extension. You see dot coms with the word "directory" in them. Perhaps loandirectory.com, phonenumberdirectory.com, domaindirectory.com... (these are made up)
In a perfect world, you could take out the "directory" and assume that the .info will give you these kind of results. loan.info, phonenumber.info, domain.info....
When a domain name with the extension make complete logical sense, I think the percieved value of the extension can be overcome by an endusers marketing.
Some examples of this from my own portfolio would be IPOstocks.info and TerroristThreat.Info. However, this hasn't caught on yet and .info resales are hard to come by. Hopefully in a few years.
Goodluck
