I've been using raindrops for over one year now and paying the yearly subscription for it. As soon as I saw this deal on Appsumo I bought it because I see Superdense as very good alternative to the current solution I'm using. On the plus side it's possible to build a profile with your recommendations which could be very beneficial down the road for blogging or influence purposes. The software allows you to change just about everything from email, user name, design, etc. It seems to be setup to prosper in the market.
