When I first heard about blogs I struggled to get my head around the whole concept. What made a blog different from a normal website? I quickly grasped the key differences - the diary style articles, the comments and the easy interface for adding new content. It all made sense until I hit something called a "trackback". "What the dickens is a trackback?!?" I thought. I looked around for a definition and nobody could provide an answer I quite understood. When I really want to learn something I go ahead and do it. I took action with my new blog and sent some trackbacks to other bloggers. Later as my blog become popular it was sent trackbacks. Having experienced both receiving and giving a trackback I understood what it was all about and felt much better.
