It's no surprise that shopping is one of my favorite things to do in SL. It can be pretty fun to try out new clothes on your avatar and see how they look. You can even play around with styles you may never consider wearing in your first life.
I recently discovered a very active blog called :ShopaholicFeed.com
I do need to warn you that if you add this one to your feed reader, it will explode as there are lots of entries daily. So go check it out.
