Thanks Karen.
Yeah, I know about wordpress being the best for SEO, and actually have a site with wordpress and was going to set up my site through that.
It was way too much work compared to having a hosted cart like SupaDupa or Big Cartel. There's always updates to do, plugins to buy and update.
Also, I'm a terrible lazy blogger, so tumblr works great for me. I know it's not the best for SEO doing it the way I'm doing it, but really, I can't stand all the maintenance that comes with a wordpress blog.
I've also heard they're really easy to hack because they're so popular, whether that's true or not, I don't know. I'd rather leave all the worrying and updating to SupaDupa, Big Cartel and tumblr.
