Not only will I continue to vouch for this plugin, for exceeding my expectations, but this last update has made the plugin much, much better. Prior to it's last update, this plugin was very useful, but it's user interface was bulky, slow, and extremely sluggish. Now, it is light-weight and very responsive.
Before, I stated that I was willing to buy the PRO version, when App.net integration was supported. App.net support was added a while back, and I've purchased 4 licenses for this plugin. The Pro version has a substantial draw, with its ability to post to multiple areas within the same social profile. However, as beneficial as the pro version is, using the Google Plus and Pinterest APIs is a substantial security risk.
