There are so many different platforms, we're investigating quite a few on which we can reach more like-minded developers and share our open source project.
We launched Applozic (applozic.com) 'Chat & Messaging As a Service' for developers on product hunt. Results were good, we got some traction and feedback from there.

Best response we got is from Android Arsenal, if you have something for android developers, post it on Android Arsenal. For the first week, on an average we got around 40 signups. We are still getting 2-3 signups weekly from the site.
