I have found so many interesting threads to respond to, that I don't have enough time in one session to answer them all. So I click the 'heart button' to save it under my 'Favorite Discussion' tab which is located at the bottom of my page. For me, it has gotten so long and unmanageable now, I've had to decide which ones to keep and answer and which ones I have to close (uncheck). Do you take advantage of this feature, or do you have other issues? Do you only follow certain contributors or topics?
