I'm so excited!
Last Wednesday, an active user on Mi Yodeya asked on meta about trying out Codidact. By the end of the day it has something like 18 votes, which is a strong show of community support on this site.
On Thursday (by which time it had picked up a few more votes), this same user proposed it on Codidact's "site proposals" section. Several people participated in that discussion, including Isaac, the founder of Mi Yodeya (who is one of the moderators there). Isaac also posted an answer on the Mi Yodeya meta question commending my involvement.
On Friday it was pretty clear to us on the Codidact team that the proposal had the support it needed to go forward. We tested Hebrew fonts and the lead developer added a Hebrew keyboard for typing posts, adapted from a userscript a Yodeyan had written for use there. (Eventually Stack Exchange took that script and built it in, so not having it would be a regression for our users on Codidact.) We tried to figure out what to use for a logo.
Saturday night after Shabbat we talked about some final details. Sunday morning we launched the site.
Monday I had a brief conversation with somebody at Sefaria about their source linker, a server-side package that finds citations (like "Genesis 1:1") on web pages and turns them into links to source texts on Sefaria. After a bit of poking and a code review we turned that on. Much excitement on our site ensued.
It's now been a few days, and Judaism Codidact is going great so far! We're still having some initial meta discussions, including what data to import from Mi Yodeya and whether to broaden scope in certain ways, but that doesn't stop us from asking and answering questions right now, which people are doing. People I miss from Mi Yodeya are showing up, and I hope in time more will. I've missed my friends. I've missed being part of this community.
We asked Isaac to be an initial moderator on the Codidact site, and he wrote a thoughtful explanation of why he accepted on Mi Yodeya. This is the model of collaboration and cooperation. Online Jewish learning is not a zero-sum game; Mi Yodeya and Judaism Codidact can exist side by side, working together to spread knowledge and build community. I'm delighted to have him on Codidact along with Mi Yodeya.
