If you know you can build a good website and you know you can market it well and know a lot about SEO then why waste money on a .com when you can buy a .info for way less? If people judge your site soley based on whether it's a .com or .info and nothing else then they're idiots. That's just my take.
.info is not so valuable in my opinion , is cheap this is why is popular but is not a good extension for me
here is one I sold the other day on sedo - buyphentermine . info I think there is a good investment possible in LLLL.info now for those who want to make a quick profit in 1 year, buy for $1 & sell for $20+++ even several hundred...
I think that if you have a really good site with lots of information about something then it's definitely worth it.
