A blog is a great way to waste time.  The blogger gets to waste their own time and if their lucky, they can waste a reader's time as well.  To raise the ratio of reader:writer, the smart writer will spend as little time actually thinking about what they are blogging.  If I can type for 3 minutes a blog that is read by 100 people in the same amount of time, that's 5 hours of human life wasted.  5 hours and 3 minutes if you're really paying attention.  I actually wasted 6 minutes because I had to retype it.  Don't ask me why.

Things I've been thinking about blogging about...

things discovered on wikipedia, such as a list of people who's obituaries were published before their deaths. 

For instance, Pope John Paul II is the only known individual to have their obituary accidentally published on three different occassions before their death.

Marcus Garvey had a stroke, an obituary was published by accident, he read the obituary which was not very complimentary, and had another stroke and died.

And the most important obituary to be published ahead of time is Alfred Nobel's obit.  His brother died and an obit was published on Alfred which referred to him as merchant of death for his invention of dynamite.  It's believed this greatly encouraged him to create his Nobel Prizes, thereby making the world a more Peaceful place.
