Simple Upvoting tool for your app, OR course, OR book, OR newsletter,...,... [Pl validate]

Hi all,

I am planning to build a simple upvoting tool for all kinds of simple needs which require only minimal features. Fewer features also mean they are less headache to use for your users as well.

Visitors come to this feedback link, upvote a couple of options, and leave.

Here is a basic design I made to get validation & suggestions from you all. Would you use a tool like this? If yes, please vote, if not, please tell me why.
