From pagerank 0 to 1 with little effort

Hurrah!!! At last my pagerank increased to one yesterday. I having been blogging for more than a year but didn't know about the necessary evil of the web pagerank. Last month I came to know about it from a forum. I then started to try increase my pagerank.All I did was to submit my blog as a signature in comments of blogs which do follow. Viola, my pagerank is 1. Now, I am going to try increase it more by submitting the url to forums and social networking sites.
