Show HN: Gem to search for random domain names (github.com)

Hi, I just created this ruby gem that creates random domain names and tells you if they're available.

Is there some reason that it outputs to names.txt? I'd rather it output to stdout, and let me decide whether to save it or not.

This is a really cool gem, great work :)

The only issue I have noticed is some of the domains it generates are not actually available because they're too short, for example 'im.li' or 'li.in'
