Not a lot to report.
Incremental improvements — go play with the site — didn't make
youpatch.com hugely successful, and we didn't pivot in a big way, but the site's still there and gets used. Occasionally there's a flurry of quilt designs created as new quilters find the site and tell their friends.
I experimented with making more traditional quilts using random-ness and symmetry, but haven't released that software commercially.
I found Racket terrific for the reasons mentioned in the talk, but because I didn't take anything else commercial — I've mainly been doing non-tech work of late — so I haven't really upped my Racket game, although I continue to tinker and learn as time permits.
The changes to Racket occasionally broke something on the site, but those changes were easily fixed.
