I've been on a 3 year fixed rate mortgage here in the UK. The first 3 years are something like 1.8%, after that it goes up to something like 3.6%.
The idea is that you remortgage every three years at no extra cost, so you should be effectively paying that lower rate for the full term of your mortgage, that is unless the economy tanks and interest rates go through the roof...
I wonder if you could apply this to social media, but with outrage instead of funny?
It'd be a good exercise to look at an outrageous personality's tweets over the years and see if the same thing happens as they slowly adapt to realising that saying worse stuff gets more attention.
