Twitter invented in 1935?

Ha - not only that, but the "Notificator" (love that name) had a revenue model!!!

OK, but how do you tell your friend which notificator to go look at? While you're telling them that, couldn't you just tell them the message too?

Twitter's main point is that you automatically get updates from people you like, not that you can post things in public.

Twitter is just one decent take on real time pub-sub systems, which has been around for a while, previous incarnations include mailing lists, usenet groups and various forums etc. Twitter simplified the pub-sub of short messages from/to mobile devices and takes advantage of the aggregate knowledge. I think Twitter will be successful (profit!) in business marketing/networking, simply because it makes pub-sub simple.

I personally will probably never create a twitter account to follow or be followed because I'm more comfortable being a private explorer/observer (reading thousands of feeds and commenting occasionally)

Twitter was invented when they first used the smoke signals.

No.

Oh man - I was listening to public radio this morning and the guest actually said that he thought the inventor of Twitter would go down in history alongside Alexander Graham Bell and Samuel Morse.

It's mildly innovative, but let's not go nuts here..
