What changed with the Mystery Box Upgrade and Easter 2015 updates?

One thing I would like to add is that they also nerfed the blue house farm (and potentially all house farming?) The cost of the house seems to be growing with the number of them you have. Bulding a blue house now costs 216000 for me. While the other houses are still at their low price and those are the ones I only placed once.

Kwik-E-Marts, Brown Houses, White Houses, Purple Houses, Krusty Burgers, Blue Houses, Pink Houses, Orange Houses and Gulp 'N' Blows now costs an increased ammount of money depending on how many the user has.

What's the "Surveys Are For Monkeys" task referred to in the update list all about? Googling doesn't bring up anything...
