FWIW, the Amherst internal blogging/social-network site is called "planWorld", and it quite literally grew out of .plan files. Around 1999, someone decided it would be a good idea to have them be readable over the web, and so they hacked up a PHP app to expose people's .plans on a web interface. Eventually it grew the ability to post, to check who's been viewing your plan, to style things, to send private messages, and to have group conversations, but the terminology is still "finger" and "plan" and "whois".

Until recently, it was also possible to go the other way: you could finger [email protected] and it would show you what I'd most recently posted through the web interface. But planWorld recently moved to a newer server which isn't running fingerd, so that functionality has disappeared.
