Why do the devs feel the need to constantly change everything?

Just one example: It used to be, until recently, that when reading the forums on PC, if I wanted to get a quick snapshot of a user who had posted, I just click his or her username, and it shows rating and basic profile info. If I wanted to actually reach the user's profile, I had to click again, and only then would it take me away from the page I was looking at. It made sense. It was convenience, and I got used to it. Now that suddenly works differently, and my ingrained patterns are going to take a while to adjust.

This is only the most recent example, and while it is not site breaking for me, it is just one in a long line of changes that seem completely arbitrary and ultimately pointless, adding no actual benefit or value to the chess.com experience, just one more thing to have to adapt to.
There have been other changes as well, from the way game review is displayed, to the addition of pop-ups suggesting to add friends, to the super annoying delay of the first chess board sound effect in a chess game when a page loads, to where I hear the "game start" sound AFTER I have already made my first move....

The list goes on.

1. WHY do the devs have this incessant need to change things that work just fine, and

2. WHAT are some other examples of seemingly arbitrary, unnecessary, or even detrimental changes you can think of that were just suddenly present one day.

I'm guessing that's a bug and will likely get fixed

Thank you for the reply Martin. In a way I hope so.

I agree...when I perform a "Review" of my gme, it still gives me an option to "Retry", but it shows the preferred move arrow on the screen before you "Retry" so...yeah... And SO Many other things just change day-by-day

Another example, in game review, there are little chess history factoids that display while the engine is loading the analysis.... these factoids appear and disappear too quickly to read them. Just another example of a "feature" that might have sounded good in the boardroom but failed in execution.

I can't stand the worthless evaluations, like when you swap a piece, a little message tells you that you did good by swapping an even trade of pieces. But that isn't a goal in itself. Sometimes swapping pieces is a good thing, other times not. There is no context for the comment. Big deal, I got an even trade of pawns. Is the resulting pawn structure good or bad? No info. Lame.

Say something intelligent or don't say anything.

The mini-profile pop-up has been fixed now

This might be of minor interest for more professional players, but I am annoyed that they changed the way in the training. Former you could see how many points you made and still need to get the next stone, you'd get rewards if you solved some difficulties and there was a firework when you got a stone. Now you only see the the progress in a line and sort of highlight after the 20st stone. Much less fun for me.
