I made 20 Gs (£20,000) in dividends on my Celebdaq portfolio.
The dividends system has changed from today too, you now earn dividends for any time you hold a share (the longer the better though). This is much better than the previous system where you only got paid for shares you held from Tuesday lunchtime to Thursday midnight (never understood that one).
Also, they are going to introduce mini-leagues soon where you get to compete within a small circle of friends. This will make it much more fun in my opinion, I might not be good enough to be top in the country but can certainly have a chance of being top amongst the people I know.
