Forum OpenACS Q&A: Response to askme.com style modules?

If a  "general ratings" module is built, then it would be a good
idea to build in hooks to allow tracking of who is doing the rating.
Not everyone will want this functionality, and in some cases they
most emphatically will want to keep things anonymous, but it is
useful sometimes for KM purposes to know whether the person
doing the rating is, for example, an identified expert in the topic or
a novice. In other words, when somebody rates something as
useful, it's often worth asking "Useful for whom?"
