Some of you may have noticed that my avatar has changed. The old one, the Scottish flag, simply vanished. Turned out the site that hosted it has also vanished. I did a quick search and found a site with a very similar name (3D flags), but when I clicked my choice it came up with one of those tiny notices at the bottom left that it was transferring data from Facebook. I don't use FB or Twitter, so just closed the page.
I may be an old cynic ("less of the 'old' please...") but I'm guessing that if I use that avatar in more than one place, FB is given that information. It also showed a link to a site called anyorigin. com, whose site gives no info that means anything to me ("Same-Origin-Policy? Not on my watch. cross domain jsonp access").
That's why you'll be seeing Wile E. Coyote giving his gravity lessons for a while yet
