Meta, won't comment on the site, won't click. I'm fed up with this category of click baity titles that are designed to be enigmatic rather than informative.
The guideline do not mention this, apart maybe from:
If the title includes the name of the site, please take it out, because the site name will be displayed after the link.
I'd prefer HN if we made it a habit to editorialize such titles consisting solely of a Domainname or a single word.One of the worst I've seen was title editorialized from original "Someone: something [x.com]" to just "Something [x.com]".
The actual header on the page is
> We are building the multiplexer for all work.
imo this would have been a better way to do the HN submission title (with or without [terminal])
> Superlogical: We are building the [terminal] multiplexer for all work
