We launched on Product Hunt. We got several hundred of new users, and all-in-all it has been successful. At the start of the day we were 2nd place, but we saw as Europe started to slow down, and the US started to wake up, we got less traction and we ended up a bit down the list.
The interesting part is that compared to many launches of ProductHunt we get a lot more visitors and new users relative to votes. As someone said, vote ups on ProductHunt is a popularity contest and don't mean anything.
