As promised a while ago, we are open sourcing our platform. A first version is now available at http://storytlr.googlecode.com with a detailed set of instructions on how to install.
With this code, you can host your own storytlr on your own server (or on a shared hosting environment). By default, it is setup as a single user mode, but you can easily change it to a multi user host and therefore reproduce the exact service we are hosting on the current storytlr.com.
We release the code under an Apache 2 license, which is non restrictive. This means that you can do anything with this, even create a successful business :-)
If you have questions, issues or ideas, please post them on the mailing list. We will do our best to monitor and answer them. We also count on your help to provide support to other users having trouble installing.
We are looking forward to your feedback and plan to keep on working on this in the next weeks to bring it to a stable 1.0 release.
Thanks a lot for your ongoing support and tweets,
-Laurent and Alard
