Captcha coolness!

I hope no one's noticed it, but we've been receiving more and more Stupid Spam Comments.  It's usually something like "I have been reading your excellent blog.  I have learned a lot...." etc.  There's always a link to "my website" at the end...but if you click it, they've captured your email address.

  It's really irritating to think that someone programmed a computer somewhere to find blogs like HH and paste that drivel into comments. It tricks new readers, and irritates the shit outta me.  Argh!

Of course, there are ways to thwart SSC.  The best way is to make real readers prove they're human by asking em to copy distorted words (which computers aren't good at, but we are).  It's called a captcha.  

We're not getting tons of SSC, but its way more now than it was two months ago.  But here's the cool part:  Larry showed me a TED talk by the man who invented Captchas, and what he explains is fascinating!  He says individuals all over the world typing two words help to digitize books.....trust me, its well worth the 15-20 minutes for him to explain.   So now I'll go switch the sign-in and word recognition ON.  I apologize for asking you to do it, and thank you for bothering.

Evidently I can comment, but blogger didn't challenge me ☺.  Maybe one of my sisters would try it?  C'mon!
