Flare was a great plugin, but in the most recent update (1.2.3) the authors decided to add a purple lightning button that looks like a social sharing button but is an actually an ad for a company called Filament. I actually had users message me via my site asking what Filament was all about, and why I was linking to it. They were confused by it. And rightly so.
So I've rolled back to the previous version, which doesn't force you to display advertising, and hope that the plugin authors remove the purple button from the next update. If they don't, then I will have to find another plugin, which will be a shame because I do like the way Flare looks. For now, though, I would avoid Flare.
