I just noticed it's been close to a year and over 2600+ people have used my AI powered domain name generator - AIDomainSearch
My biggest win was posting AIDomainSearch on Hacker News which drove close to 900 on a single day!
I have posted AIDomainSearch on various startup directories like BetaPage, BetaList, StartupTracker, Owwly.
I have recently joined IndieHackers and am hoping to promote AIDomainSearch here as well.
I intend to promote on technology showcase directories as well. DjangoSites (since, AIDomainSearch is built with Django) worked out well for me and got over 200 hits.
