for those looking for another open source task tracker, taskwarrior[1] is a good cli option. You can use VIT[2], curses-based front-end to taskwarrior. I don't use VIT, but taskwarrior integrates nicely with vimwiki using taskwiki[3].
why isn't there an OAuth system that is purely GPG keys based. For example I could sign some custom message from the server using only my keys, without ever having to deal with emails.
This way sign-up is as seamless as login. Is there anything like this I can use? Are websites not doing this because of spam and other issues?
there are ways to get over other forms of trust, for example: use being pseudoanonymous. There is no way around video, unless you happen to wear a mask.
isn't this more like "An open source Firestore alternative" right now. Do you plan to bring other features as well?
I'm a big fan of firebase and use it whenever I can. The reason it's appealing it because it's the suite of tools and how well they work together for bootstrapping (auth, firestore, storage, analytics etc). No single feature by itself is useful to me.
I would definitely switch if this atleast had (auth + db + file storage + functions).
It's very rare to find those "scratch your own itch problems", the solution to that itch is most likely a google search away.
Pick a good product that you use and clone it. Keep an open mind because you can never copy the entire business since there is only so much you can see. Atleast you get some direction to start and you know that you are not trapped in building something people don't want.
Since you mentioned making your skillset strong(technical?), either way you win by just starting something.
