I remember seeing this plugin somewhere, but don't quite remember the name. What this plugin does is simple. Say I have 10 products. I will write a line or two about the product on the homepage (let's call them "summaries"). The plugin will create a "vote" button next to these summaries. If someone votes up any product, the summary goes to the top of the list (based on the number of votes). Someone votes down, the summary goes down. This is much like a question and answer sites we see online. More votes = more popularity = on the top of the homepage. In short, I want to give users the option to vote the product they like. Any "new" user coming to the site will definitely find this useful.
