Google Prefetching for Mozilla Browsers

    I can see employees being confronted for browsing pages they never actually looked at. An obvious example: innocently searching for info on the silly Vin Diesel movie "XXX" turns up a nice mix of Vin and pr0n in the top results. Presumably a mix of both are loading up in the background

      You get people upping bandwidth costs and slowing down browsing time because the site maintainer THINKS they'll go to some next page but the site design actually ENCOURAGES them to go to some other, unrelated page.

      There are extensive studies from third parties on what people look at and do when they search on google. And you know what, they found people tend to look at and go to the top result, and don't even glance below the top few results most of the time.

      I'd expect that a company with the means to do the necessary research wouldn't go about implementing this kind of hackish "feature set" until it had thought things through a little better.

      I'd expect that Google has better figures on where people go to from Google's search pages than anyone else.

      Prefetching is one of those things that seems like a really great idea on paper, but doesn't hold up so well in practice.

      The page you cite in support appears to be an argument specifically against prefetching pages with the rel=next attribute. As you say:

      The problem is that you have things like 'rel=next' that expect the user to go to some next "logical" page, but no structure to a site to encourage that logic.

      That's a flaw in firefox's prefetching logic, not in site-designers' use of rel=next, which was never intended to be used to indicate links the user was most likely to follow.

      In any case, google is actually using rel="prefetch", which *is* intended for that purpose. And google's use looks pretty sensible: "This tag is only inserted when it is likely that the user will click on the first link." From experimenting it appears that it's only used on some searches; e.g. the example they give is the first hit on a search for "stanford". So presumably they have fairly good evidence that a user is actually likely to click on such a link--I suspect they have enough data on this that they don't need to just guess.

      In OSS, a lot of the maintainers and coders are just "hackers" or college kids contributing bits and pieces of less broad knowledge over a bigger project team, not real software engineers who have been trained to really think through the consequences of certain design decisions.... I could see why someone at Google might think this is a good idea, but I'd expect that a company with the means to do the necessary research wouldn't go about implementing this kind of hackish "feature set" until it had thought things through a little better.

      I think you're making some huge generalizations here based on very little evidence.

      Your post is confusing. First you say that prefetching doesn't work that well in practice and present a link to Simon Willison's blog. But the blog says that prefetching is an "excellent feature" except for a couple of quirks in Mozilla's implementation. Google does not trigger those quirks so they are irrelevant.

      Then you go off on a tangent about how "real software engineers" think through their design decisions more than "open source hackers". This is totally contrary to my experience. I would more highly rate the software engineering of Mozilla against Internet Explorer, Unix versus Windows or Apache versus IIS. I could go through a long list of brutal design decisions in commercial software that did not hold up in the real world but I'll just mention Clippy and the Windows registry as two high-profile examples.

      Finally, it is Google, a commercial software services company that is the topic of the article. So your whole argument is self-defeating. Either Google doesn't conform to your vision of real software engineering or the feature is not really at odds with real software engineering.

    Does somebody knows whether MSIE and MSN collaborate the same way?
    Anyway it could be obvious that Google tries to establishes such alliances against his main concurrent (besides Yahoo).

    Ever heard of the concept "one click and you're guilty?" Users of this feature who unknowingly perform a search that returns results containting offensive/illegal content may find themselves being prosecuted by local, state or Federal authorities...

    Proof of concept: Google caught in anti-Semitism flap. Replace "anti-semitism" with "child pornography" and you'll understand what I'm getting at...

    Unless :

    You have an ADSL line with a really stingy cap (for instance BT in the UK offer a cheap service with a 1GB/month cap). I'm sure their customers will be happy about downloading pages they won't read.

    You're a web admin that pays a lot for bandwith. I bet they'll be really happy that lots of people will be downloading their pages without ever looking at them.

    You're at work surfing through a proxy that does filtering / logging and there are some dubious sites that get pre-fetched for you. Enjoy getting sacked for something you didn't do!

    Well, I don't know about you, but I'm struggling to see any drawbacks to this great new technology!
