Behavioral Targeting: the most underused technique in today’s marketing

It doesn't look like you've obtained permission to duplicate the design (and you've stripped it of the ®). I like the way it links through to a page which exalts people getting 'good karma'. Indeed.

I also noticed that whilst you linked through to XKCD for using the comic, that's pretty much the bare minimum you can do to satisfy the attribution requirements for his Creative Commons: it'd be better to include a small text link since it's not immediately obvious that the image links through to the source, and if I didn't know that it was XKCD I might think you'd come up with it.

In general, I find this approach incredibly annoying. Usually I would rather see the canonical version of a given site.

Hypothetical example: because I'm running Linux and in the US, a site shows me content/software geared towards US Linux users. However I am trying to find a solution for a Windows issue with my girlfriend's laptop, who is based in Ireland.

And a similar but different anecdote: Steam has consistently refused to let me pay for games with my US credit card while I'm in Europe. I have to use a VPN for the payment to process. Wat?

It might indeed have quite a lot of potential but on the other hand I am already annoyed when websites are geo-ip'ing their language setting based on my "alleged" location. But maybe enough behavioral targeting is going to segment myself into the leave-me-alone user group.

Not sure if these opt-out cookies have much effect but anyways:
