I think if you want your visitors to come back to your website or blog it must be attractive for visitors to view. At blogger you got enough choice. There are always better looking ones. I prefer this template for my blog, because this template fits my blog's URL.
I found this site GOLD FISH this site offers info on how you can start a online business. I think you got to check out the free web template page it contains more than 2000 web templates.
I think the site site has poor content. For the money making tutorials you do not have to be here. For the web templates it is the place to be. If you are looking for new, fresh looking templates give the site a visit.
