Nice to see this here today. A number of hosts the article mentions are on the startpage of lookit, a finger client I've been building: happynetbox, plan.cat, thebackupbox's finger webring, etc.

The start page exists because finger has no discovery layer. finger @host lists users. lookit makes that list selectable, so you can wander a server instead of querying one address at a time.

I just released a v0.2 beta, feedback welcome: https://github.com/jonathandeamer/lookit/releases/tag/v0.2.0...
