I have started working on something that I think is interesting. There aren't enough flat-file blogging platforms around that support full integration with social media. I have decided to create my own version of this with the Envoi Project. This project is currently hosted on GitHub, but will soon have its own website.
The idea is to focus on centralized content sharing. No matter what type of team or group you are trying to share, you will be able to reach everyone with a single post.
Another huge topic I want to focus on is security. Since you will be syncing your social media with Envoi, securely storing your credentials is very important.
The project is in an infancy stage at the moment, but I am hoping to gain some traction soon and get a working project released before the end of the year.
If you are interested, follow the project at GitHub.
