Each week we give technology developers the opportunity to tell us journalists why we should sit up and pay attention to the sites and devices they are are working on. This week it’s file sharing site Pownce.

 1) Who are you and what’s it all about?
Hi, I’m Leah Culver, co-founder of Pownce.

Pownce is a social messaging website where members can send messages, files, links, and events to their friends.

2) Why would this be useful to a journalist?
A journalist could use Pownce to distribute a link to a story and get feedback. It’s a great way to gather information and share ideas.

3) Is this it, or is there more to come?
There are plenty more features on the way including a more complete API and a new way to view links and files.

4) Why are you doing this?
We started Pownce as a better way to share stuff on the web. We were very frustrated with the current methods for sharing files and decided that we could do better.

5) What does it cost to use it?
It is free to use, but if you’d like to share very large files you can purchase a pro account for $20 a year.

6) How will you make it pay?
Right now we make money by selling advertising and pro accounts.
