Examples:Imagine coming to SE tomorrow and instead of seeing 1 2 3 4 5 ... 77 next at the bottom of the questions page, you see a giant circle with a triangle inside pointing to the right and you no longer have the option of going from page 1 to page 5 in one click, but you must now click the big circle incrementally instead.Or imagine your favorite weather website having a 10-day forecast horizontally across the screen like a calendar would have, then one day it changes to a vertical alignment because someone decided it was time for a change.Questions:Why do people do this?  And is it normal to feel extremely frustrated by this?  I mean, when something works well and makes sense, leave it alone?.  Why change stuff just to change stuff?  And especially when the change is less functional or intuitive.
Why are websites constantly updated even when the change seemingly reduces functionality?
