That said, there might be the occasional rogue app or web site, which should be uninstalled or avoided.
How would I know if a web site is "rogue"?
This was absolutely unintentional and involves at least two intermediates over which the original blogger had no control whatsoever.
Link to the page in question: http://fh2012.tumblr.com/page/6 It so happens it's the tumblr blog of the current favorite to the French Presidential election, and it was the first post so I noticed it :P
I would have preferred a web in which scrolling (and certain other operations, like the Back button) was always instant regardless of how the page is coded, and consequently I did not have to watch out for rogue pages or sites.
ADDED. Or at least a web in which there were fewer ways for a page to go unresponsive, which would have made it easier for readers and writers to anticipate responsiveness problems.
