When I decided to create a blog, I knew there were a few major free blog players out there. Google/Blogger, WordPress, etc. I chose WordPress because (a) it had the largest, most straightforward looking homepage, and (b) when I visited http://svec.wordpress.com it had a big friendly button that said “Create Blog.” Done.
That’s some good UI design – I had no excuse not to create a blog here at WordPress, and it was oh-so-easy to just go ahead and do it.
