I am over at Twitter Right Now

Well I am following over 1900 people and I have over 73 followers at Twitter. Over at Myspace I have over 4200 friends. I have had more people from Twitter go over to view various different websites of mine. Where should I put most of my effort? I would think that Twitter would be a better place to look for followers. I have also decided to view people's websites and leave comments at Twitter, in hopes that I can increase my PR rating for this website. I do not think that a current PR ranking of 1 is that impressive, considering that many of my Squidoo Lenses have PR rankings of 2 and 3. My other Blog - Marketing Online Business also has a PR of 1. This has to be increased as well. So, it is off to blogging again.
