.plan is the historic unix equivalent of todays status on social media.

you would write your status (or what you plan to do or whatever) into a .plan file in your home directory,

and you could use the finger command to query the contents of that .plan file from other users on the machine. or on any other accessible machine.

plan.cat appears to be an attempt to make that feature accessible through the web, complete with the ability to create an account and add your own .plan file.

not what i would go for. i would much rather prefer something similar that i put on my own webpage. (well, technically, all it would take is to agree on a standard url like https://my.home.page/plan or something like that.
