This 'free' plugin is just a ploy to get you to buy *extremely* expensive "add ons" to the very same plugin. Features that should be built in to begin with. So far, there are 2 additional "add ons" to this plugin that you have to pay for.
While the social media buttons are pretty enough, they don't work as well as most of the other social media sharing plugins I've used (shareaholic, flare, et al).
I'll be going back to Shareaholic. I'd be asking for a refund of the add on I bought for this plugin but as it's not likely to get an answer, I'm not going to bother.
DO NOT buy into this cheesy way to get you to pay for plugin features that should be built in to this plugin already. Makes me feel like the dev is sleezy.
