and as a result:
1. I don't know if I've answered questions for them before.
2. What their level of experience might be.

4. Whether the person would be a worthwhile to try and convince to answer questions or volunteer.
I think this site is really starting to loose sight of the original intent "expert's EXCHANGE" (collaboration between people), as you are now hiding identities. Great way to build a sense of community (NOT).
Not sure why we ran with this, but it doesn't seem well thought out and I for one will not be answering any of these questions.
