It's all about finding the right avenue to put them up. You will find tons of newly registered .infos available on eBay for $0.50-$0.75 each. This is disappointing to a certain extent because it suggests .info are not serious at all. All are variations on viagra, forex, investing, etc.
Nevertheless, I have sold some powerful keyword .info's for $20 that I hand regged. At the time they were great deals for me but I wished I hung onto them. Interesting they were bought on eBay by serious end users.
I will be acquiring more .infos both hand regging and in the secondary market because the extension is so fitting for my goals and it is so natural to set up mini-sites for them. I am not looking to become a millionaire, but using my tactics I am and will make extra money each month.
