I was doing a little research on Yahoo Site Explorer on a widget provider that is claiming some pretty big traction (more on this later). In the process, I did a reality check of backlinks against MyBlogLog.
MyBlogLog is showing up as having more than 3.5M backlinks.
If these guys would build out a destination site with some landing pages that people actually search for (as opposed to MyBlogLog profile pages), they could turn a fire hose of organic search traffic on.
This is a great example of how successful widgets can be a tremendous aide to your site's SEO / Linkdev efforts.
