Well you have a point,
For me the user wall feature was lame, I dont use it beacause frankly I did not know its specifci function. I think we can actually do better than the user wall by dropping it and then considering the whole social features from scratch. What social features would you want to see in powerqa?
For me, I prefer social features that inetegrates into existing social networks,
1. Can I auto post my answer/question/topic to twitter or facebook or any social media?
2.Can i just login smothly with any social account,
3.Can i invite my friends on any social media to powerqa?
3.Can I point a discussion or question to a particular user?
4.Can I do something to get more interest in my question/discussion?
5.Can I re-ask a question someone asked if there is no answer or if I dont like the answer?
6.Can i do anything to re-open a question that was closed without a very good answer/reason
etc
Thats the kind of social features I would want to see for a start,
What about you? Can you explain further exactly how the wall post was used in your case and why it should be maintained and improved as a social feature?
Thanks
