i think you should focus on build a proper chat because people that are newbie and want to learn how the site work, may find useful to talk and ask to someone, the first step for the success is to improve the support over everything else, first
This is an awesome idea. There are too many complain about errors and bugs and many people do not how to use the site yet. It is very great to develop a chatting system which can help users to solve these issues. Looking forward to seeing 1xBit improve this function
