Related Articles Widget for Blogspot and Other Sites, from Blogspot

Putting in related links to an article keeps your traffic into your network or site. The longer they stay, the better chance of conversion.

Well, there are many BlogSpot or Blogger related article widgets out there but they often refer to it as a hack or something like that. I think differently, something with a publicly available API isn't a hack, it's a valid widget or mashup with javascript as a client.
