The advertising we display on Siafoo helps pay for the cost of running and developing the site.
Since we abhor flash-based advertisements, huge banners, deceptive ads, and most of all those ridiculous 'intellilink' things, we have attempted to display the ads in places where they make sense and in ways that will not annoy or distract you. In fact, a major motivation behind implementing the Articles feature in Siafoo was our annoyance with the prevalence of busy, flash-based ads in existing tech-article publishing sites.
You are, of course, free to use ad-blocking software in order to prevent the ads from showing, but note that most sites you use on the Internet today are free because they are funded using online advertisement.
Please let us know if any ads are showing in weird places or in annoying ways, or indeed if you have any other questions or concerns.
If you are interested in advertising on Siafoo, please drop us a line.
