I completely agree, and again want to advocate an even more advanced threaded forum solution, where you can have email abonnements. I mean there are good reasons why github issues are designed the way they are, and there are good reasons why github is very successful in the marketplace.
But still many people love the tools they are used to. It's understandable and in some ways also efficient inertia. Anyhow, i think it is time for a change in the way community communicates. I'm completele inline with you on this.
