1-2 hours a day I like general chat the most unless I am searching for business info or have a problem needed sorting
It usually sits in the background so I get timed out a lot. But I would say 2-3 hours of steady use per day.
is my 5th day in DP today. and i realize i spent my time here about 10hours per day. before this i always go to facebook.
I spent nearly 2 until 3 hours a day, i also browsing somewhere else, so i can't ensure how long i spent in DP There is too much things can be learn in DP.
