It's still there! I'd recommend gopher://gopher.floodgap.com/ as a starting page these days, it has links to SDF, Veronica 2, and a lot of other Gopher resources. It's pretty easy to spin up your own Gopher hole with pygopherd these days as well - I re-hosted mine a few weeks ago and could't have been happier with the ease of setting it up.

There are are lot of defunct Gopher holes, but a couple times a year I still get lost browsing through a mix of old and new ones. Install OverbiteWX in Firefox and take it for a spin sometime!
