For me, It will cause a huge uproar! cause even me is using myetherwallet.
If it will be close! all of my tokens and my eth is there.
I will be mad if it will be close.
Also for the other users who use it
Just so you know, MyEtherWallet is an offline wallet with some online functionalities. Which means your coins and all your tokens will be safe even if MEW close down.
