Hi, I am a community manager for various Twitter and Facebook accounts and all have seen fantastic growth since I took them over. I also write for various websites giving me a great advantage with being able to talk to the press and schedule reviews.
I would be happy to take a revenue share or upfront deal for promoting your apps I have a couple distribution channels, many review site contacts, etc. But of course that can all be discussed later.
Email at firstname.lastname@example.org or PM if you're interested in working together.
