(This is partly-related to 'FusionCash' or 'Support,' but it branches from a general complaint about laziness.)
Quite regularly, content-delivery/distribution-networks (CDNs) have frozen my browser. First there was/is the 'akamaihd'-CDN (used by Facebook). Then there was/is the 'wsrcdn'-CDN, used by Wiser Surveys.
Computer-geeks
claim CDNs do complicated feats to deliver content to info-seekers across the whole-wide `Net (http://en.wikipedia.org/wiki/Content_delivery_network#Content_service_protocols), but it comes across as more like 'webmasters redirecting info-seekers to other servers (which redirect them to yet other servers etc.)' And Firefox reads that as an 'unresponsive script.'
The way it's supposed to be is end-to-end (http://en.wikipedia.org/wiki/End-to-end_principle):
application-specific functions ought to reside in the end hosts of a network rather than in intermediary nodes – provided they can be implemented "completely and correctly" in the end hosts.
