The way it currently works is, when I'm going to make an article I run a report like this:
Find all the plants that meet a certain criteria, like in this instance for example, they have "Annuals" selected. Now you have your pile of plants. Then for each of those plants, count up how many individual members posted a photo or comment to each plant. Then sort by how many you found and there's your popularity contest results.
I figure the more people photograph and comment about a plant, the more popular (or the more grown) the plant is.
So, apparently not a lot of people are photographing and talking about petunias yet in our database.
