Exceptionally insignificant. Not only because hardly anybody reads it (which makes it safe for me to spout my mouth off about anything - very cathartic), but because:
On July 31, 2006, Technorati tracked its 50 millionth blog.
That means that if you have a blog, it's 0.000002% of all blogs out there. (That's five zeros after the point.)
If a small country like Belize (population: 287,730) wanted to keep up-to-date with all the blogs on listed by Technorati (which isn't an exhausted list of all blogs) it would have to assign 174 blogs to each citizen. Luckily Belize has 240 miles (386km) of coastline with white sand beaches, warm crystal clear Caribbean sea and fantastic diving so it doesn't have to.
