Problem is that there are much more lucrative monetization gamification models than advertising, which spam and intrude on users less. Advertising is going to die and be replaced with superior gamification which is more attuned to users' preferences.
Interesting! Do you have any examples of "lucrative monetisation gamification models"? Conventional online advertising seems to be on the verge of death indeed.
Why bombard with banner advertising when you can recommend/mention/link to something (preferably which is entirely free to start using, and which itself uses gamification to earn revenue) within the context of your content which your reader really needs and then receive an affiliation income from which is much greater than the income from spamming readers with shit only usually less than 1% of readers are even interested to click on. In other words, highly targeted advertising without violating the privacy of the user to track their interests and without bombarding them with banner ads.
In case someone might conflate this with Synereo's and Tsu's plan to pay social networking users to share, the salient distinction is that the social networking user is there to share to gain the synergies and love/reputation whereas the blog or publisher is focused on publishing (and monetizing his work so he can continue publishing). Also the social networking user doesn't have reach of readers of a publisher, unless of course he has a high reputation of sharing things that so many others reshare. So one could see some social network publishers arise, but this can't be a model to pay most of the users as I explained in the Synereo thread.
