Developers really love doing all these forks - but they are a massive nuisance for everyone else. The exchanges, the online wallet providers, the payment processors, all of them have to do a shedload of work to accomodate these changes.
That's why I think coins that don't change much (bitcoin, doge) will end up being the winners. People just want something that works smoothly and that you don't need to do a lot of work to maintain, so that they can focus on the eco-system around the coin.
Apart from the problems faced by Coinfloor, the show must go on because it is clearly not possible for the ETH developer team to cancel the hard fork process, which preparation itself takes a long time.
And in my opinion, there will be many other major exchanges that will support the hard fork process. Moreover, the hard fork process carried out by ETH is an effort to overcome the problem of the Difficulty bomb (ETH Ice Age).
