Been discussed several times before - and the answer depends on the purpose.
For keeping my own log book for my PPL flying, not attempting to get any licence or rating or anything, I choose to log as XC time if I draw a line on the map. If I just "go flying" locally without doing any actual navigation (other than looking at well-known territory out of the window) then I choose not to log it as XC. Thus my log book tells me how much time I have spent "navigating" - it doesn't tell anyone else anything very much.
