Nothing special about users here. However people's behavior can be very different in different environments; what people do in real life isn't always what they do online. So:
- Go through user-behavior and retag the few questions that are not about online scenarios (if any). I haven't checked all the questions, but the sample I looked at was all about online stuff except How do I help members of a community focus on work when they want to be social?, which is about physical meetings so I suggest meetings.
- Rename user-behavior to online-behavior and drop the user-behavior name.
“Problem” is kind of a subset of “behavior” here. I think a lot of these questions should be tagged online-behavior in addition to problem-xxx. As for the xxx, I think continuing on the “members” theme is fine: rename to problem-members and drop the synonym.
Could be renamed to member-retention, or just retention. “Retention” isn't just about members, it can be about other actors such as customers, but I think that in our community, “retention” is intrinsically about members.
Monica suggests a distinction between member retention and something else — I guess audience retention. I'm not sure about this. Should we have member-retention, audience-retention and maybe even the intermediate participant-retention? It feels to me that we're getting out of community building and into marketing if we get that serious about non-members.
This thread shows that some people are not familiar with the meaning of “retention”, so we might want to throw in a synonym, but I don't know what. Please suggest what you'd use if you aren't familiar with the word.
I think we can safely drop user here.
This is about experts. Just rename to experts.
User experience is a concept. Keep.
