Take this simple, contrived example:

UserRepository.GetAllUsers(); UserRepository.GetUserById();

Inevitably, I will have more complex "queries", such as:

//returns users where active=true, deleted=false, and confirmed = true
GetActiveUsers();

I'm having trouble determining where the responsibility of the repository ends. GetActiveUsers() represents a simple "query". Does it belong in the repository?

How about something that involves a bit of logic, such as:

//activate the user, set the activationCode to "used", etc.
ActivateUser(string activationCode);
