I've seen a number of groups on Facebook which were created with the sole intent of connecting webmasters who want to promote their websites. You help other webmasters promote their sites and earn credits which in turn will get other webmasters to promote your site. The promotion could be as simple as liking a web page or sharing content from the site with [your] social media connections, bookmarking sites like Stumbleupon, etc, etc. All you seek is to have more people see your content and theoretically the more your content is shared on social media and social bookmarking sites, the more readers you might draw to your blog, website, etc. Do you think this is a good way to promote websites/blogs or is it a waste of time?
