The Blogger Builder used to have a Wordpress site (which involves paying for web hosting) because "everyone" says that they WP sites are much better, with more options, and more plug-ins, and they give you options that Blogger doesn't offer.
If you look at the main network of sites that I personally run (ChicagoSportsWriters), you'll see many things that you didn't think were possible to do with Blogger (and its FREE hosting).
I offer inexpensive quality site building on Blogspot for people who want to blog for free with a nice-looking site. Check back soon and this site will be up an running 100% and you'll see what I mean!!
