No, I have a not overly poor php background, html, css. So I am biased towards a WP site more now. Actually, its been like a day and I love adding all those mods and playing with them in the template.
Get a blogger ! easy to use and you dont need to be a net geek. Trust me. ( btw google provide blogger and you can trust googles equipment.yup)
Go for wordpress becos there's so many things you can do with it. There's a lot of plugins and themes available to choose from.
if you want a fun and free blog, choose blogger if you are a serious blogger, go for a self hosted ordpress blog. Wordpress.org (self hosted) requires you to pay about $5 a month for some web space.
Well the differences are : Wordpress has it's own tag publishing system except normal ping services Blogspot uses technorati and other common ping services . but wordpress are more strict about the content being posted. everything that is suspected to be promotional post might cause your blog to disabled and you will loose it with no warning
