I’ve never been a big fan of Google’s Toolbar PageRank (TBPR) because, as you may know, it’s a metric that isn’t updated very often. It’s also been thrown around too much as a metric that gauges quality — and I’ve been doing this long enough to know that many lower-TBPR sites/pages (and new sites with no TBPR) can be incredibly beneficial for sending you traffic that converts.
Relying on TBPR to determine suitable link partners eliminates loads of good stuff. Let’s say that there’s a great new post that’s unranked, and it would be a perfect fit for your site, but since it has no TBPR yet, you just move on. That post could get tweeted 10k times, and if you’d had a link there, you could have potentially gotten 50 new customers.
