I have three monitors. Two big, one small. But purchasing new hardware is not a suitable solution for someone's programming oversight. (a.k.a. blunder)
Chess.com's Biggest Blunders

chess.com's reliance on TinyMCE - Javascript WYSIWYG Editor is beginning to appear blunderish - since it goes AWOL from time to time.

The whole site goes AWOL from time to time. I can think of no other site which I visit regularly that has as much down time.

There's not much unscheduled downtime though.

Do you spend a comparable amount of time on any other website?

But, if it's blunders we are talking about, then I have to return to the playing board. Not only is it off-center but there is all that information that is hidden from me such as moves, captured pieces and notes. I have to click on a tab to get to see them. Like it would be bad for me if I could see them. And if I want to see the rating adjustment I have to click twice! All the other chess websites put all that information on the screen where you can see it in a glance. But here all we see by default are the discussion messages which usually remain unchanged throughout the game. (at least with me) The main feature here at c.c is talk/social interfacing about chess. And it's good! It's good to see all this talk about chess. There's far more interesting talk here than at other chess sites. I play vote chess here and that's about all I do here anymore (besides keeping an eye on artfizz's latest topic).

I don't know why you have to click twice -- I'd asked before and I was told that it was because the calculation is CPU intensive on chess.com's servers, but I still struggle to see why the raw data couldn't just be sent over and the calculation done on the client side.

Do you spend a comparable amount of time on any other website?
Hard to say. I probably spend more time here because I spend a lot of time reading comments and analysing positions in vote chess forums and I sometimes use the explorer db. The group/team chess thing is very good here at c.c and that is due to the social atmosphere. I don't find that at other sites. Another good thing is that the discussion is always about chess. (almost always) I play almost all my personal games at four other sites mostly because I like the playing boards better (appearance and function) and also because they use Elo.

You're not implying that he's the cause of the downtime, are you?

Remember this discussion ... ?

No need for separate Analysis and Conditional boards:

And if I want to see the rating adjustment I have to click twice!
Oh, the horror!
Just curious-- how many times do you look at the rating adjustment during each game?
I hardly ever think to look at it, partly because I don't care what my rating is, but mostly because it wouldn't make any difference to me if I knew the adjustment anyway. No matter what it is, I'm still going to try to find the best move each time.

It is certainly no great effort to click twice and the rating adjustment is not something I am obsessed with. The thing that bothers me is the thinking and planning and philosophy and additional programming that went into this unnecessary feature of the playing board page layout which gives chat priority over all those items of information which actually apply to the game which is being played. There is plenty of room on the page for all of that information. In the age of computers it's all about info. It is also about choices and user friendliness. It would be a fairly simple matter (from a programming standpoint) to make the arrangement of the game board page user definable.

Even with the current design, it would be more convenient if the game page could remember which tab you had displayed and made that the one that first displayed when you next accessed the game. in my case that would almost always be the moves tab. As was pointed out above, for most moves there hasn't been any new text added in the messages window. Maybe it could be set so it only defaults to that window initially if there's been a new message added since the previous move.
Hey, while we're at it, how difficult would it be to indicate on the messages the move number at which they were entered? There are lots of times that would be handy to know that later.

The biggest blunder is that spell-check program of chess.com thinks that there is no such things as Viswanathan Anand.

@artfizz - yes, I remember that forum very well.
That was when I submitted this suggestion; ...
One of the discussions was fully-integrated-game-explorer?page=4. What was the other one?
Man, buy a big enough monitor you won't even notice it.
p.s. Seriously, you won't regret the expense.
