All of my homebrew utilities have been pushed to Github, everyone else has largely fallen out of interest or has been busy unfortunately. My work was largely homebrew-related, getting WUT functional and doing homebrew installation stuff.
Eh, there hasn't been hardly any notable Wii U homebrew recently. There's some small games here and there which are great, but a lot of it lately has been dumpers, launchers and emulators. Forks are helpful when the original developer has lots time/interest, but when the project is only a few days old it's really better to contribute to the original. It's a courtesy thing, not a "why not?" thing. And, this is just me, but I think the community really needs a more easy and well documented custom firmware, not one that is more complex.
