Here’s an interesting chart I came across by following various links from the wordpress front page.
It shows the popularity of various blogging platforms.
As you can see, blogger has an early lead, and is still growing slowly.
WordPress has gone from nothing to be t he leader by quite a margin.
Moveable type (DPF’s old engine) has gone from a distant second to footnote.
Typepad has alwasy had a small following, but you have to pay for that service so that’s not really suprising.
No idea why there’s a jump late 2008!
