Have you heard about the bitcointip bot on reddit? Users are able to send tips to other users by creating an automated address for the users who want to tip another user. Users who have bitcoins in their account send bitcoins to any user typing “+/u/bitcointip @Username (amount)” in the comments thread. The user who is sending the money can formulate the amount either in Dollars or in bitcoin. Here is an example how to tip an user. “+/u/bitcointip @cooluser $1″ or “+/u/bitcointip @cooluser 0.01 btc” So, why would such an add-on add value to the community? Of course I can not predict the future and I am not 100% sure if the communities would use such a system but the reddit community is heavily using this system. That’s why I am assuming that it could help any user based content community. It adds good charma to users who contribute value. This value adding system should not only be tight to bitcoin but to any of the well known coins such as litecoin, peercoin, dogecoin... Do you also think it could help to motivate users contributing good content to the community?
