I think that the .info is a very good domain, it first started in Oct 2001 and has 1, 006,000 registered domains, but look at what is happening with the numbers game .us has 463,000 and it opened only in April 24, 2002. Half the time, so they are selling at the same amount as .info and .us is a country domain!! What does this mean, well .us will be the biggest country domain in the world. The rest of the world uses there Dot country like .uk, .jp, .ca and so on. So when someone in another country is looking to find WallStreet they will go first to .com and then they go to .us because they are so use to there dot country that it's natural for them to use .us to look for WallSteet. Also look at what just happen with .kids.us read the story
http://www.bizreport.com/article.php?art_id=3910 President Signs Dot-Kids.us Legislation. This means that every kid and parent will learn that .kids.us is a domain that is safe for children. But this also means that every parent will learn that there is more .us domain names and will get interested in seeing what web sites are out there with the .us. Now what if you owned a company that sells computers or computer software and are interested in getting some of that traffic. Parents and kids will just type computers.us in there browser, just to see what is out there in the .us. The same goes for Mp3.us or
WallStreet.us and so on. So keywords in the .us will go up in value.
