It makes sense to use .info if you're providing information. I can see extensions and expected usage becoming much more defined with .info the biggest beneficiary. At the moment people use .com like sheep even when the keyword is more suited to .info and they're not actually selling anything.
The three dominant extensions are going to be .com, .org and .info with country codes for local services. .net is a dinosaur with no obvious use apart from as a second rate .com, .biz is a joke, and .mobi is technically obsolete because the Internet is already mobile and browsers will downsize standard content for mobiles and handhelds without users having to go to another site with a .mobi extension.
