It’s not so much that Nikola Tesla discovered AC as much as he figured out how to make use of it. I believe generators give alternating current by default as they spin around, but they’d use commutators to convert it to DC.

Source: saw one of those Discovery Channel shows.

Either way, Tesla was a brilliant engineer, but it shouldn’t take much to understand that it takes energy (that has to come from somewhere) to produce electricity. That money has to come from somewhere, and I wouldn’t want to see a gigantic factory or mansion or whatever paying the same amount (even if $0) compared to some grandmother in Vermont keeping the lights on.

It could use some UI/UX work though. For example, if I want to go to a comment I replied to from my profile, rif had a handy button to show my comment with context. On Jerboa I need to go to my comment with a couple unintuitive taps, then the context of that comment with another button that doesn’t really feel like it’s in the right place.

I’ll give it time to develop though
