After it has worn of, a lot of people left. But all the "big names" we now have in Bitcoin are people that joined in 2011 stayed and started to build stuff.
This time 100th the times of people joined, and if the same % stay and work on making Bitcoin more useful we will see the fruits of it in 1 - 2 Years. But the hype has to end for this, including the mining hype, so people start looking for other means to get BTC.
And what did the community get? Mining is exploding to the point it is about to collapse on itself, payment processors going on and offline with uncertainty around most of them, investments which are mainly based around mining hardware pools or investing in other investments (which are generally mining pools). Other than proving that greater influence of outside interest (read: $$$) can change a market and that BTC is basically only still existing to self-perpetuate, not sure what "the next step" can be for v1 of online currency when there is no great demand for it.
Oh, and "pre-orders". And missing chip deliveries. And knock-off hardware. And scams on eBay/Amazon/anywhere you can sell stuff. And ponzi investment schemes.
Exactly:
Just look at this forum. Bitcoin is currently all about mining. If I click on unread posts 90% are somehow related to mining.
I hope when this craze finally ends we will see more actual stuff about getting Bitcoin adopted again.
