Regarding reddit, you can replace "www" with "old" i.e. https://old.reddit.com and it is still functional. There is also a firefox (perhaps chrome too) extension that replaces it automatically.

I don't know how long it will last, but if it's gone I think I'll be off reddit. I tried to use regular UI few times, and the experience is absolutely off putting. It reminds me of digg right before people flew to reddit.
