CrowdA - are they ahead of their time?

Have you ever wondered how long the concept of social blogs will live? The scheme by which Habr works, including when a lot of authors write original texts for free and publish them on Habré and other similar resources. How many years will the “war for content” begin? At what stage of the development of social blogs, the authors want to get something for their work? At what stage of the development of the site network will they understand that authors need to be somehow stimulated and preferably with money signs?

The idea of ​​rewarding content authors is not new in and of itself, but today only the CrowdA service provides a workable model (if there are analogues, please indicate in comments).
Briefly about the service itself and the models of mutually beneficial cooperation between publishers and content distributors (Contributors).
For publishers, there are two schemes for remuneration of distributors, the first is a return of a certain percentage of ad impressions and the second is a fixed daily budget for your site (the amount of the budget can be adjusted even every day).
At the first work scheme, a publisher has very flexible settings for his account - which banner impressions to give, how many, on which pages, different types of content can be set for different reward schemes (as an example for viewing pictures one percent, for reading news - other percent). It is also possible to set individual profiles for each author - articles of one attract a large audience - a greater percentage to him, etc.
With the second scheme of work, everything is much simpler - the site owners simply indicate a certain daily budget and it is divided among all the contributors to his site.

This service was originally conceived as a global one, a registered agent registering once in the system receives his ID and can work with all the sites registered in the system, funds earned by him from several sites will be credited to one of his accounts and payments are made at the beginning of each month, it is worth noting that the service makes payments not only in PayPal, but also in WebMoney.

What is the benefit for publishers? Believe the word, I am telling you as one of the publishers who tested this service, after entering the reward system on the website, the amount of content increased by 20% on average, besides, the contributors themselves began to promote their news on third-party resources, which led to a significant increase in resource attendance . Attendance increased - advertising revenues also increased, even against the background of the fact that part of the income goes to contributors, the total profit of the site increased. Again, in principle, I myself would be able to make such a system locally for my site, but then the question of payments arises, there is no desire to bother with payments to hundreds of authors myself, so I prefer to use the CrowdA service for these purposes.

If anyone is interested in the service - all questions can be asked by email - support@crowda.com, you can write in Russian, English and Hebrew :-)

I have one question for everyone - is there a future for such services? Soon the era of free content will end? Consider how many authors - specialists in various fields can be attracted to the network as content distributors - for them, the threshold for entering such a business is zero!
