To be honest, I was looking at a short name, something than "Rustacean" would get, had a domain name available, easy to pronounce. I didn't like rustclaw, I think having similar name doesn't mean much unless it's very related, like tinyclaw being a typescript simili I get it.

For the logo, I do think everyone went for the lobster meme for a connection to clawdbot. But in my case it's because I wanted to use a derivative of the Rust logo, a crab.
