One of our site visitors sent me a "Twitter" invitation of some sort last week.  I like to think I'm pretty "with it" as far as technology goes.  I've got, of course, my cell phone, I'm a voracious texter...I don't have a Facebook or Myspace page, but I do know how that all works...it just seems pointless to have a Myspace or FB page since I've got this.  But I'm having a real hard time getting my mind wrapped around what "Twitter" is.  I first heard of it in April when a student used Twitter to twitter his way out of jail.  But I still didn't really grasp how he did it using Twitter.  I've gone to Twitter.com but their explanation of what their own service is, I think, is pretty lame. Does anyone use Twitter?  If so - can you explain iin dumbed down English what it is? What is it's point?

Also, thanks to all of you who are contributing their "marriage tips" on yesterday's posting. I think I was just in a bit of a semi-melancholy mood, not over the marriage itself, but over the "mechanics" of it...in short, I just don't want to screw it up.  So your tips are really helpful!
