Yeah, turn around online and someone will tell you don't write a press release without being newsworthy. That's not a realistic deterrent.
You're going to be able to squeeze just as much link juice from Squidoo as you will from PRWeb or any of the other large PR distro companies. People will always publish mediocre sub-par releases for link value. Why? Because they see it as a short cut.
From what I've seen, you can still eek SEO value out of it. But, Tom is right. The only SEO-value I would consider to be long-term is external online pickups.. editorial mentions from sites outside of the normal distribution network. Don't count on PRweb.com link lasting or passing full value.. or any value for much longer.
