Eh, your account is still tied to an instance. That instance stores your subscriptions, as well as the vast majority of your preferences. If you want to get way into the weeds, that’s why Jerboa won’t persist comment sort order, but other clients will - there is a server side prefer for all/local/subscribed and new/hot/best at a post level, but not at a comment level.
I take it you live somewhere that’s fairly sunny year round? We had a visit from a door to door solar salesperson stop be recently, so I dug in a little. We get a little over 6 peek solar hours in the summer, but come winter we’re down to around 2. Our energy use last month was about 25 kwh/day. There’s basically no chance of us generating all of that :( Add in a third of that being my plugin Volt, which charges at night, and it’s really not looking good for generating all our own power.
