Nice update this time! 2 sites less than 3 weeks old gone from N/A to PR2, CSS Gallery & I Love Lyrics nice start for them! Anyone else have a new site that jumped so much?
I guess you just had good timing with launching your sites and doing some link building. I also jumped from PR0 to PR2, but my site is almost 2 months old. I'm not too excited about the PR2 though. I know the lower end PR rankings are very easy to attain. As your PR gets higher, it becomes progressively tougher to get to the next level. I care more about serp's and traffic anyway.
Good work! I won some and lost some - just like life I suppose! I agree though that people get hung up about PR - its serps, traffic and ultimately profit that counts! PR makes a site more valuable
This could be that PR update around same time the site was setup & you have build up quality backlinks in this time.
