I love the new look. I never used SmugMug because of the older design they had.
I've been looking for a easier way to build a photography based website and I've been trying to maintain a Wordpress one, but I find it much too complicated to get it they way I like. SmugMug makes it easier, and simple.
I do like that Wordpress has a blogging feature though. I may just create a SmugMug page and just have it redirected to a Wordpress.com style blog for now.
I'm going to try Square Space too and see if that's just as easy since it has a blogging feature built it.
You can check out my SmugMug
here. It should be working now (I recently transferred my domain name to Godaddy from Bluehost), as the link was coming up blank for a while.
