It was used at a business seminar/conference in 2006 apparently. Has great cartoons and some important points to note about blogging.
This one, however, struck me....
It is true that edublogging requires a bit of the old passion and authority.
Passion to maintain your blog even when the going gets tough and stressful at work.
Authority to make your views known to the world and to make controversial points at times.
You can view the rest of the slideshow below. Enjoy :)
UPDATE: Cartoons used in the above Slideshow are from Gaping Void (thanks Graham for that link). There are some really witty ones if you wade through the crude and odd ones :)
The other Blogging cartoons that I LOVE come from We Blog Cartoons.
