1. Yes and I did about a year ago. I think I'll find it hard if I have to go back to 5 days a week. It's really nice to have long weekends every week. I've time to work on other things and take days to go hiking or skiing. It makes the work week really fly by as well. Some downsides are having to catch up on everything you missed on your day off, so it can suck up time. Also it takes people a while to realize that this is a permanent thing and to stop inviting you to meetings on a Friday. I would highly recommend that you pick the same day every week and stick to that. I picked Fridays and marked my whole calendar as out of office that day. Otherwise its too hard for others to manage if you take a Monday off one week and a Thursday the next.

2. Yes. I did this too. Although technically I negotiated to reduce to a 32 hours week instead of a pay increase. But I have the option of going back to a 5 days week with a 20% pay increase. Software engineers generally earn pretty good wages so I'd prefer to have the time than the extra money.
