The whole point of having a tilde.team account (for me) was to have a place where it is easy to provide content using the Spartan protocol. So... here it is: spartan://jdcard.tilde.team. Eventually I hope to find a way to set up a Spartan server on the same host as my website.
Since I'm now focussing my efforts on the Spartan protocol it is probably a good idea to point folks to appropriate client software. As of mid-June 2022 I am thinking that Lagrange is the best choice for a GUI Spartan client for Windows, MacOS, Linux or BSD, and I'm still trying to decide whether I like Bollux or Offpunk for use in the Linux console. UPDATE: I liked Bollux better, but I've just compiled the TUI version of Lagrange (clagrange) and it works great in either a terminal window or in the Linux console, with features and user interface comparable to the GUI version; recommended! I haven't found an Android client yet, but Bollux works in Termux there. If you don't have a Spartan client you may still read it in your old-fashioned web browser using the Spartan-to-HTML proxy at portal.mozz.us/spartan/.
A tilde.team account provides lots of other nice features for folks who like to keep things simple*, including a minimalist blog server. Here's what there is of my blog in the tildeverse.
* - "Simple" in a Linux sort of way. There is an old story of a Linux user who responded to a complaint that Linux is not at all user-friendly in this way: "Of course Linux is user-friendly! It's just picky about who its friends are."
