well lets say if you get 100000 AdSense page-views in a mouth and about 1% (1000) click on an advert (might be a bit more depends on ad placement on your site etc) and the Cost-per-click is at least 1.50 cause its heavily saturated with advertisers (there are AdSense keyword price checkers about just google them) then that's 1500 a month minus your hosting costs --- just looked on your nice website very good on the advertisers section its got an email address a GMail one i recommend you get one from your hosting company I.E you hosting should support making pop3 accounts or make an email forwarder that you can always forward to your google account
It is obvious that website traffic is worth the effort and time if you want to drive traffic to your online business. That's why my answers would be definitely 'yes'.
