SEOmoz has a couple of very interesting charts showing the top 500 domains and the top 500 pages being linked to from different places. This paints a pretty good picture of what sites are held in the highest regards by content producers.

"The sorting is done in order, not of raw link counts, but of linking root domains - a metric that we've found incredibly valuable both for identifying broad popularity (vs. sites that simply earn lots of links from a few sites with many pages) as well as filtering spam (it's easy to get lots of pages linking to you, and even easy to get lots of subdomains linking to you, but getting a diverse set of root domains is considerably harder)," explains Rand Fishkin of SEOmoz.

I'm not going to replicate both lists of 500 here. You can view them at SEOmoz, but I will provide a quick glance at the top ten of each:

Graph by SEOmoz

You can get a look at all of the stats like linking root domain count, external link count, mozRank, mozTrust, PageRank, and change on the charts. Fishkin also provides some interesting highlights from the lists like top gainers and losers here.
