Today is my blog's 1st birthday

One of the blogs which is Bogart's Online World, will celebrate it's first birthday today. It all started way back in November 9, 2008 when I created my first ever blog and post about making money sites. Most of them are paid-to-click sites, HYIPs, revenue sharing programs and much more. In that time, I have no knowledge about web optimization until I joined webmaster forums called Digitalpoint which there are lots of SEO topics, and this is where I developed and applied to my own blog. Today in a shock, my blog has rose to PR3 on it's homepage and PR2 on other pages without using search optimizing techniques. Now I have a feeling that my blog will rise soon in the search engine ranking pages (SERPS), which is all about general internet topics.
