If I may also contribute, I find this type of activity to be a major inconvenience, and often times infuriating. Here are three examples: Clipboard hijacking: Remember Tynt? They hijacked your clipboard to say "Read more at <link>" or some nonsense. That is not what I copied, and you are breaking my expectations by modifying it. Gruber has a much better post on this (http://daringfireball.net/2010/05/tynt_copy_paste_jerks http://daringfireball.net/2010/05/tynt_copy_paste_jerks), but essentially: knock it off. Don't try and manipulate your reader. Information panels: If I doubleclick a word, it's because I'm marking my place in an article, or I intend to copy and paste that word. To offer any sort of popup or panel gets in my way, and causes me annoyance. This is not the expected behavior, and I'm far less likely to continue reading the article or website if this happens. Tracking: I don't know how bad yours is, but with Apture it was just one more company tracking me. There's already Google +1, Facebook like buttons, and Analytics on every page - and this is just one more thing to slow down my page and turn my data usage into statistics. I don't like it. I can enable Noscript, but I shouldn't have to. You may say that these are features that your users (Cloudflare customers) want, but I'm sorry - they're morons. I deal with clients who would eat these kinds of features up, "they'll set us apart from other websites!". No. It only hurts the end users, and does not provide useful features. And it really concerns me that Google bought Apture, I often use Chrome and do not want to see this integrated at any level. I can see marketers and managers eating this stuff up, but it surprises me that the engineers at Google are interested.
