even though no one says they care anymore, I bet most people prefer a link from a PR site than a non PR site if they can get it. I like getting PR links you need to understand that having a good PR doesn't mean traffic and it doesn't mean rankings but it's a good indicator for how you site is viewed overall by Google, and it can be used as a bit of leverage when doing work for clients and showing them how you have a good PR on your site even if they don't understand what your talking about.
