for each feedback or bug report the admin (Microsft ) will add a rating (normal,good,verygood,excellent).
Normal:feedback that are general
Good:feedback that are helpful
verygood: feedback that improve the product funtionality
excellent: feedbak that will change future of product and came with new idea of innovations.
e.g.
please make color of Microsoft Connect website to blue(normal)
Microsoft Connect website should add new feature to be accessable by mobile phone,in this case you could ...(excellent)
Then people with higher rating and more excellent and more feedback would recommend to involve in other Connection Website Program.
Example of benefit: Microsoft Windows 7 Technical Preview was avalable privatly by Microsoft Connection Website. Many user asked you how can I join Windows 7. Here it is , if they are very active in other connections and give several excelents then why you are not invite them to this program? In otherhand , if you have a look at member of Windows 7 Technical Preview there are people who are invited but they didn't provide any feedbacks or activities, I don't say you get them out of program but you could also invite people that are active in other connections and I am sure many of them help product to do well and add more features.
For active Members you should give reward by promoting them to other private and invitation only programs such as Windows 7 Technical Preview or in future in Windows Operating System. People who are active in one connection and do great , then they probably could be great help for other connections. Their Witnesses are their feedbacks and their excelent mark(that I suggested in beggening). Also you could find more MVPs and enhance your products a lot more.
