I miss fingering, it was such an easy way to get a log dump or status update from various daemons, I still think it has immense utility .. some of my fondest operator days were sat under the umbrella with a terminal while sleep 30 ; finger someone@all-the-things ; done .. watching the machines from afar.
Can still do it these days of course, but one with a seriously copious helping of ssh in the mix too ..
Trouble is, nobody else can do it. The only reason I have to use {social-media-blob} is because my friends don't know how to finger.
