I spent a little time checking out the latest privacy imposition from Facebook which means flicking through screens, opting-out of various ways my personal information can be used to "personalize" sites I never visit.  Anyhow, much like the highest court in the land  I have discovered the Intertubes is a scary place. I could be a well-trained dog, for example. Or you could. Or we all could. Scary!
But what to do? Get an impressive-looking seal, that's what. Now all you keyboarding canines out there can rest assured that documents that cross my paws, er, "hands" are 100% certified and legit. Just look for the seal!
I am told by my human companions that forging such a seal would be nearly impossible unless you have opposable thumbs and one of these:
(Ha ha! Thumbs! Like that's ever going to happen.)
If you are engaged in Monsieur Packer's analog letter exchange thingus, and you receive a poorly-spelled, blotchy, rambling letter claiming to be from me, don't believe it!
...unless that poorly-spelled, blotchy, rambling letter also features that stamp. Then you know it's the real analog deal. (Yo.)
 You might argue that Facebook is by design an invasion of privacy, and I'd agree with you. It's also darn handy for keeping up with old friends. But that's all I want the site to do with my information, thanks.
 Hey! I'm 40 now. Bring on the grumpy old man act.
 Email? Text messages? Who can keep up?
 It also helps if you have a great deal of patience for picking up tiny rubber letters with a pair of plastic tongs, and picking up said letters after spilling a tray on your desk.
 The letters are perforated, so I'm not sure what the razor blade is doing in there. Maybe to end it all when you've just spent far too long picking through tiny, inky type trying to sort out the "i" slugs from the "l" slugs.
