Don't just stop joining hackathons but select what suits you.
for e.g. events organised by Startupweekend (http://startupweekend.org/) They start on Friday evening and end Sunday evening exactly what you asked!
From my personal experience !
It didn't fail. It's just not successful yet ;)
There is a difference so keep working on this and any other idea you have.
Very very useful!
Would you mind giving some details on where you hosting this ? I am also working on a Django project and struggling to decide hosting service to go live(Personal project so cant start with $20/m plans)!
