I don't know why I'm waxing rhapsodic about this, but I am. Webdog retired at the end of February, but I didn't notice 'till now.
Back in the good ol' days, .plan files could be finger'ed to query information about a user. The first "blogs" were born from these ASCII files spewed from UNIX servers scattered about. This mainly caught on in readable popularity as John Carmack and others at id used it for talking about random thoughts, product announcements, server downtime, etc.
However, Carmack has since moved out of the .plansphere and into the blogsphere, and I'm sure Justin Frankel isn't far behind. Or maybe he is. He seems to like the obscurity.
Me too, I guess.
