Usually if I see a project archived on github, I move along and look for something else. I learnt the hard way that there is a high cost in those cases, we would definitely want to use something actively support and we won't mind paying for the right tool.
I have been long time Django/Flask users, and undoubtedly a good web frameworks give you some structures, security and impose good practices to new programmers, that's what I'm trying to find out. I'm not very aware of how advanced Go Framework are, but if there is something that could replace nicely my current Python web stack, I would be happy to give it a go.
If there is One project where a lot of developers would want to hack is definitely their own editor!
It's a big dilemma, I love the idea of seeing an open alternative but I also love the possibility to support developers working on what they love!
One problem that raise here is that we haven't find a way to ensure that open source projects can bring an incomes to their maintainers, even if there is many users.
