I would like to outline few facts.
1 - Imgur is not responsive either, responsive is refereed to sites which can scale or dynamically change there site layout/structure based on active Window view. A responsive example is Twitter Bootsrap CSS Framework. Imgur however is NOT RESPONSIVE.
2 - Imgur does not retain FILENAME either
3 - There aren't many Imgur API based applications, there is at-least few for every-device for ImageShack.
4 - There is no life-spam on files there removed in term to TOS violation
5 - Rape quality? Really. Imgur does not allow GIF > 2MB, ImageShack has no problem with GIF > 2MB and it has yet to "RAPE" image quality. I am sure you never been "RAPED". And using the word that has nothing to do with "image quality" is out of place.
6 - WTF? Where have you been living? ImageShack had Flash and HTML support for years. So I am not sure what you been using but its been there always.
