Increase Sociability Wordpress Plugin

I have talked to Becky from preblogging.com a while back when she was coming up with the concept of her increase sociability plugin. The concept was seemed to make sense. When users come to your site from a social voting site offer them a quick option to digg/stumble/etc your site to continue the traffic love. I had some concerns though. Social voters can be really fickle and I wondered if it would annoy them to be reminded to vote for your site... or if the pop up might annoy them to auto vote against your site.. The good news is people that are running it say its a great success and are quantifying it. I will be implementing this plugin soon and will report back on what I am seeing. You can download the plug in here I am interested to hear your thoughts on a plugin like this?
