Are site profile links from sites like Quantcast still a Google friendly quick win?

I heard one of the speakers from Link Love suggest getting an easy high PR link from Quantcast.by creating a site profile page. What is everyone's opinion on the value of this type of link when blended with other types of link building activity. Low, Moderate?

What is the best way to find these types of link profile opportunities? Any one have a good list?

Used to be huge, pretty sure most of them have been discounted greatly. Case in point: Google ignores links from updowner (which is one of those whois/site stats sites). My guess is that they do the same for all of those types of sites.

But you have inspired me to run a test to see how effective they still are
