Have been using this plugin for a long time and despite some of the negative comments about the call to home this is still the best share plugin out there.
Looks great on the website and works perfectly. The author is really supportive too and actively works to resolve all issues unlike many who just do not even bother to respond. Have to agree with mattrock1 "No 3rd-party subscriptions required, with lots of settings and configuration options". Setting up social sharing comes with many issues and having tried and tested many of the other WP social share plugins really believe you cannot get a better plugin than this.
