It would be nice if you had a way to demo it without putting it on the bookmarks bar. Maybe already running on your site, or launchable from the installation button (instead of telling me to install it).
I'm using Chromium 4.0.299.0 (36335) on my Mac and I get that popup too.
According to jeresig, author of jQuery, one should not perform browser detection, instead you should use feature detection. Browser agent is not going to give you an accurate picture of what is supported because every browser likes to say they are mozilla/webkit/netscape/etc.
Also add Namoroka and Minefield, test versions of Firefox. Instead of whitelisting, can't you run some test code client-side and only prompt when you're sure the browser doesn't support it?
Nice. Making the commands visible without clicking the button (but more subtle/better designed) would be nice, else I'll just forget the button is there. Good stuff. And yes, pik means dick in Belgium too.
I just installed it. I don't know how much I will use it, but it's definitely something I would use, if that makes sense. Readability, bugmenot and google cache are all things that I've never bothered to make easy before.
It looks like a competitor. Pik has a UI that's in the browser window rather than a pop-up prompt, which allows you to search for commands. Pik also shows you what commands are popular on a given site/page, which makes it easier to discover commands.
I must admit that I found the heading "Do more on the web with pik." rather amusing.
