I believe that as content sharing sites mature, there will always be a way to monetize them, similar to how advertising has evolved in websites and blogs. The challenge with blogs is that if the readers opt to use an RSS reader, they hardly get exposed to the outside-of-the-blog-post ads. Being linked becomes more of a targeted campaign to increase your Technorati authority, search engine visibility, and traffic (depending on blog popularity).
From an advertiser point of view, spending 100 dollars may be used to do any of the following:
- Run a Google AdWords campaign with a budget of 3 dollars a day.
- 10 to 15 text link ads appearing in various blogs (PayPerTextLink)
- 5 to 10 reviews (PayPerReview)
- On a social news or content site submission/vote campaign, that would be good for 50 to 100 votes or submissions. (PayPerSubmission, PayPerVote, PayPerDigg, PayPerStumble)
- On micro-blogging sites like Twitter, that would be good for 5 to 20 Twits reaching to no less than 5000 followers. (PayPerTwit, PayPerTweet, PayPerTwitter)
I still believe that each blogger is responsible for their own blog. Their blog is their own business and can do whatever with it. They are bound by their own rules, or the platforms, or of the blog networks, or the revenue programs they joined. If readers don't like what they see, they can easily tune out by not visiting your blog anymore or unsubscribe to your blog feed. The same may be applicable to social news site and micro blogging tools like Twitter.
The growth of ad networks, whether small/informal or big/formal, shall continue to thrive. It will seize on opportunities that shall promote their client's interest. We can either become consumers, critics, contractor, or creator of these networks.
