why are my earnings not increasing?

If you posted responds your ernings will defenitely increase, just wait for sometime, mylot update the earnings once in 24 hours, and the earnings for your discussions today will get added up after tomorrows update. i think it's just the time for valuation. Remember there is no shortcut to earn money here, just post some lengthy responds, you will get paid.increasing number of responds won't earn you unless it is meaningfull, and for meaningfull and descriptive responds you can get upto 3 cents as i was told from somebody else, i am sure you can get a very good earning if you actively participate here, just dont think of earnings, keep on posting, check your earnings after a week or so,you will be happy
