As it seems, people will have to search regardless. Once Market gets (hopefully) 1000's of storefronts, there is only so much pixel space on the home screen. Market wouldn't want the buyers to be searching every time. So, they will have to add a users "subscription list" like in You Tube. One searches and adds their favorite stores to their list. Every time ones comes back to Market they (Market programmers) can program it to show, on your Market Homepage, only the stores on your list plus some extras.

The only confusion I see, sort of, is Market focus on the Selling of Storefronts or is Market focus on the selling of Products?
