Product Launch

Greetings IH,

Currently building a nice niche micro-saas. Should be ready to launch in a few months or so. After doing research on were to launch, I've come across so many websites (20+) on where to launch. Is there some service out there that can take some input then automatically post to as many website as possible? It would make the launching processes that much easier, and I could launch on websites I never even knew about.

Regards,

Yaroslaw Bagriy
