Ask: What about starting a new submission type on HN called "CLI: ..."?

I think that sort of thing should be written up as a blog post and the blog post submitted to HN. If the information doesn't justify that much effort and cannot earn sufficient upvotes to make the first few pages, then it isn't really worth posting.

I would really really really not want my HN polluted with this. Especially when there are dedicated Twitter feeds to exactly stuff like this I can check.

It looks more like an idea for a new StackExchange site. Questions and Answers.

true, and yes StackExchange is part of my resources. I just thought it would be nice and engaging to post it on HN, as everyone has their surprises everyday when working the CLI.
