This is actually really interesting. Open source is the future of software and incentivizing communal efforts makes sense. Are you taking any commissions on it though?
We started off with that mindset, but it didn't really make sense as a business decision, and I don't find the those kind of fees fair for users.
For monetizing, we're working on a buildout where closed source companies can list issues as well. Which will operate more like a typical freelancing platform.
