Since there is an app, people probably pop in periodically throughout the day, and possibly show as logged on when they aren't actually actively here.
As for me, right now I am not working until I relocate within the next few weeks, Lord willing, and so I've generally been keeping CC up in a browser tab and checking in throughout the day.
Honestly, though, my attention span is fairly poor. I'm not sure yet if I'll get burned out on CC in a couple of weeks and then disappear. It happens. Ebb and flow of life and all that.
