TradingQnA can benefit a lot from allowing OpenID or FB connect
- It will encourage lot more people to participate since they can use their existing IDs
- map it to internal TradingQnA id to retain the credibility badges
- This way, people can use the same ID with Zconnect and answers/comments from ids which have higher points will have more weightage for viewers
- Maybe with social buttons in QnA, some good questions might be linked to social network sites like FB/G+ encouraging further participation from the trader community.
