Congrats, but i think PR nowadays is only worth it if you are selling links. Traffic is more important to me.
Good, this means all your hard work is paying off eventually I also got a PR5 and PR3 for my site and blog which were n/a earlier, so I am happy too.
Congratulations. I am struggling to increase my PR. It was 0. Now a question mark has placed the position of that great 'Zero' Why it is so ?
