Hostel trends 2014 - how was it for you?

Hi.
There were many new apps/websites this year but I feel like most of them have not been really meaningful and some have vanished as they came. Does any of you use/like the following:
- http://onlyhostels.com/
- http://www.hallwaysapp.com/
- https://www.hostelrocket.com/
- https://www.facebook.com/rateamate RM8

Any this was useful for you?
Thanks
