There is a lot of the use of the word "Cosmos" online... would it be good to add another word to the site name?
I think currently Cosmos is good as there is no cosmos.stackexchange.com and and already an astronomy.stackexchange.com. Most "cosmos" searches on Stackoverflow are mostly about MS Cosmos DB. We have had a lot of questions and answers related to Cosmos on different channels. I believe once the site is up, those q&a can be moved to there and make the Cosmos site very clear on what topic it is about.
Honestly, when I first saw the proposal, I thought of stars and space and stuff. Now I realize that that's not it and that the title can be a little misleading, so I would suggest changing it slightly to make it clearer!
