I have a cake I posted 4 days ago with 86 views on it that isn't showing up in the "this week" list.  There are other cakes with fewer views that are.  Anyone know what the algorithm used for making this list is??? 

I didn't know there was a "This Week" list. If you mean Newest Cakes on the home page, number of views has nothing to do with it.Cakes are uploaded constantly, so they don't stay in Newest Cakes very long - sometimes probably less than 5 minutes, depending how many people are uploading their cake pictures at one time.

Never mind. I didn't even know there was a "Most Viewed" category in the Gallery.
