i do look at the pr bar but i try not to make much out of it. it is a lot easier to get quality links from other sites if you show a higher pr though. that's about it. i believe the next pr update should be coming up soon. i forgot when the last one was but it was a while ago and i know it comes out about every 4 months. i remember when it used to come out every month, or was that backlinks? i'm too old to remember
