The future of traffic!
When the internet was young it was judged differently as far as search engines were concerned. The web spiders would crawl your page and look for keywords and other things that would give your page value. It was the best dressed page back then that got the top rankings. The problem was that alot of people cheated to get this ranking. They went so far as to build words into black backgrounds with black letters to fool the search engines into thinking they had a better looking page than they did. Now blogging for backlinks is required as the real barometer of value is how many people link to you!
