I love the overall look of this site, but not being able to see who is active makes it feel like you're just shooting in the dark if you try to pm. Of course, if people are not ok with being seen there should be an option to not put yourself on the list, but I still think one could be good for quality of life.

Clarification: Last online date is not something I plan to add. A list of friends currently online (who have the privacy setting enabled) is a planned feature.
