Well, I registered an .org domain when Namecheap gave me an .info domain for free (both with the same url). So I decided to try an experiment - I blasted both money sites directly with all my same backlinking strategies (blog comments, profile links, web 2.0, .etc) and guess what? The .info domain ranked HIGHER than the .org! I was like WTF? And yes, the .info's position has continued to stay at the first page. WTFism. In conclusion: Google doesn't discriminate .info domains! Register them as normal.
