For some level of automated updates, I have my README (https://readme.jvt.me or ie https://github.com/jamietanna/jamietanna) that provides a more recent view of things
There's a lot of stuff I track, like podcasts I listen to (https://www.jvt.me/kind/listens/) or number of steps I take (https://www.jvt.me/kind/steps/) but I don't feel like things like that should be on my /now
(I do need to rethink what is on my /now page, tbh)
