Tremendous news, a shot in the arm for a lot people (myself included!)
This is something I’ve been interested in as well, and we mentioned it over on the dev forum a bit ago.
Maybe not necessarily related to the fund, but perhaps even something simple like a community wiki for dev knowledge. Not even stuff related to the codebase in particular (which could go in the actual code docs), though it could include higher level descriptions. But also just for info on all of the tertiary things from common how-to (e.g. make a new cli command, proposing new msg types, etc.) or setting up your build environment, to centralized algorithm info once features like BRB and CRDTs are stabilized, etc.
Office hours not a bad idea, or even just a dedicated channel for questions (office hours might be rough schedule-wise for already time-pressed devs perhaps, but that’s not for me to decide).
In any case, if there’s not already some sort of wiki-esque thing out there, I’d be interested in helping to establish/contributing to one personally.
