We all know damn well there's no lack of coders on bitcointalk, and I'm pretty sure some of them wouldn't mind helping out. We already see that in the way that quite a few members, on their own time, come up with detailed suggestions about solutions to some of the problems the forum has. That way Theymos wouldn't have to spend any more of his precious time creating a fix from scratch and would only have to review the submitted code and either reject it or accept it and then implement it.
I don't claim to know how Theymos spends his time, but it does seem obvious that he ought to get some people involved. He can easily do that without relinquishing any sort of control over the forum, if that's the problem. The problem is I have no idea what the problem is with him. lol
Workload should be delegated more from a staff standpoint, but coding the forum is another thing. He did hire someone (Slickage) to do that but not sure what the status of that is and whether theymos is just doing that full time now. We still could probably do with a couple more staff (in various capacities), or at the very least some dedicated sub board mods being attached to subs like Bitcoin Discussion etc and that's something I've been requesting for a while. As for whether other people can help out with the coding side of things only theymos can answer that.
