Widget-market-leader AddThis has introduced a new feature today–the smart menu. As of today, if you use an AddThis widget to submit or Tip a story, then every subsequent share with AddThis will have Tip’d as a sharing option within the compact menu, which comes up when you hover over the AddThis button. Very cool stuff. And the effect will stay with you across the over-400,000 sites currently using AddThis. So next time you see an Addthis button on a great financial article, make sure to use the widget to Tip it!
