What about the server owners?
Hey Google, this is *really stupid*. There's not enough detail to know for sure what the effects of this will be, but it sounds like the background pre-fetching could slightly or massively increase the number of requests to the web server, based on guesswork. Any URLs loaded that are not used will screw server-based analytics. It will also needlessly increase bandwidth for the user and the site owner, both of which can cost a lot of money as this multiplies up. A lot of web pages are now generated dynamically, e.g. by a CMS, and the servers may well start to bog down - at best reducing the response time for real requests and at worst causing serious performance issues. AVG tried this a while back - pre-loading results pages from Google to check for virii - and it caused similar issues and was removed, thankfully. Fasterfox also did id and similarly caused issues. Google - think! If you think this speeds up the Internet you're wrong - it slows down servers and costs everyone (but you) money. It's irresponsible.
