Just started.  But solid is working reasonably well, as is SolidOS.  Just a few things to tidy up.  I've already done login to solid with nostr (schnorr) which I think you've seen.

The solidOS and micro apps are going very well.  Here's an example micro app, with data view (think view source on steroids) on the left, and app view on the right.  All updating in realtime.

Allowing long-lived data storage on top of everything nostr offers.  I'm even using it to host this video:
