I think this is a thing that could be very valuable for Steem.

But I also have to say that without knowing your plan on how to execute it, I am skeptical as to how attainable this project is. As we are voting for a real project with real funding, I suggest that you add more technical details as to how it will be done.

Some good questions would be:
• Who runs the code? the app owner or you?
• How does the plugin system work? Is it more like wordpress? And limited to condenser like apps?
• How many people work on this and what is their skillset?
• In regards to using agile, do you have user stories and research that you can publish? This could establish trust in the sense that yes, you have a plan :)
