Too many sharing services

Lets say you just finished reading an interesting blog post. Now you want to tell the world about it.
Usually, you will have about 5-10 "bla-bla this".
Here's an example...

"Digg This! * Sphinn It! * Save to * Submit to Propeller * Google Bookmark This * Stumble It!"

Well, That's a nuisance, and what I think we should have is a protocol for post sharing and I'm not talking about the likes of

I'm talking about a solution that will be quick and non disruptive of my blog reading. Something like the "share" button on google reader. Maybe a link that will require you to choose your sharing platform only once and from then on, it'll be just a fast one click process.

(I know about bookmarlets, but they are so "local machine" oriented, I use many PC's and devices for reading blogs.)

The Grandson Paradox

You probably heard about the Grandfather Paradox, which sparked my idea of the Grandson Paradox.
In short, the Grandfather Paradox suggests this never-ending loop:
1. You travel back in time and kill your grandfather before he meets your grandmother...
2. You will not be born...
3. You will not travel back in time...
4. You will not kill your grandfather...
5. You will be born
6. Go back to step 1.

The Grandson paradox which I thought of about ten years ago suggests this experiment:
1. Go to your back yard
2. Bury a note that says: "This is for the descended of "your name" that will encounter a time machine." Please come back to the date "date of note burial" and show yourself.
3. Swear to yourself that you will pass the existence and purpose of that note to your kids and their kids.
4. Expect to see a time machine...

What do you think? is it a paradox? or just a philosophical question?

Live press

Future news sites will have an IRC like window that will show the news live as documented by reporters on site.

Drop SAT's

I think that SAT's can be easily replaced by an academic analysis exam.
Each academic field will compile a test that's fitting for its specific needs. It might be a great non biased way of assessing success in school.
Which is the goal of SAT exams.
