I hesitate a bit but do propose this seriously. It’s definitely very cryptic, and hard to type for most people and all that. But it’s also more accurate than any other proposal in my opinion, with the added bonus of being more succinct. The domain name would be λ.wiki. I think everyone who would participate in this project would get it immediately and see the connection to lambda calculus more than with “wikilambda”. But maybe I’m crazy, feel free to tell me I’m crazy. — The preceding unsigned comment was added by Milimetric (WMF) (talk)
I don't think it would be a great official name, but I could see the λ.wiki and lambda.wiki domains in conjunction with the Wikilambda official name stylized as Wikiλambda and λ or lambda in internal use, such as a “currently in λ” news section. --CamelCaseNick (talk) 16:21, 18 September 2020 (UTC)[reply]
No - This name is hard to type, especially in mobile phone. In addition in many places (such as database name) only Latin characters can be used. --GZWDer (talk) 04:51, 17 September 2020 (UTC)[reply]
I agree this is hard to type, but the written-out "lambda" could be used instead. However, I would prefer a name suggesting the project is a wiki. Concerning the domain: The wiki will be created at either "foo.org" or "foo.wikimedia.org". This is currently undecided and will be based on technical and legal decisions. I'm not sure Greek and Latin letters can be combined in a domain name either. 𝟙𝟤𝟯𝟺𝐪𝑤𝒆𝓇𝟷𝟮𝟥𝟜𝓺𝔴𝕖𝖗𝟰 (𝗍𝗮𝘭𝙠) 18:34, 17 September 2020 (UTC)[reply]
λ.wiki sounds like a sexy modern 2020 startup domain name, I guess. At least it gives me those vibes. That could be a good thing. Regarding technical issues, the internal database name could be lambdawiki, and there could be a redirect from lambda.wiki, so I'm not sure how big of a deal this is.

I love the domain name! If I understand it correctly, the .wiki TLD doesn't allow it, though :( I checked which other TLDs would work, and found a few: λ.community, λ.studio, λ.works, λ.codes, λ.services, λ.plus, λ.show, λ.gives, λ.construction, λ.media, and my favorite, λ.church (due to Church, not church. --denny (talk) 18:34, 25 September 2020 (UTC)[reply]
I'm not sure what the benefit of this over "Wikilambda" would be. A lot of people won't be able to type the lambda symbol and both the symbol and the word lambda would be difficult to search for. I could see the lambda symbol being used unofficially and in logos though. - Nikki (talk) 16:15, 27 September 2020 (UTC)[reply]
Aw, I love the very thoughtful comments people left on my weird idea, thank you. I agree with all the practical disagreement, and I learned something about the .wiki TLD, thanks Denny. I do hope "lambda" somehow sticks around in the name and that we can use the symbol in the logo. Milimetric (WMF) (talk) 21:09, 14 October 2020 (UTC)[reply]
Support. Even though it isn't very consistent with the rest of the Wikimedia brand, I like it. PiRSquared17 (talk) 00:42, 23 September 2020 (UTC)
