Microsoft recently announced the ability to research what pages a domain links at. For example, see what pages this site links at using LinkFromDomain:SEOBook.com.
You can also use their advanced search features in combination with LinkFromDomain to look for links pointing at domains within a specific geograph region, and / or adjust the result order by popularity and freshness.
As most seasoned SEOs knows, Google gives sucky inbound linkage data. You still can get a decent sample of recent inbound linkage data from the Google BlogSearch link function though. For example, here are recent blog posts linking at SEOBook.com. Technorati provides similar linkage data.
You can get a more comprehensive view of linkage data using Yahoo! Site Explorer.
I plan on updating SEO for Firefox to include the LinkFromDomain feature and check if URLs are linked from the Wikipedia.
In addition to all of these forward and backward link tools many video content sites and social bookmarking programs allow you to use other's work to explore interesting items, which sorta brings the fun back to the web...finding all kinds of cool stuff.
As technology evolves, and more users become editors, the value of being a general editor will be commoditized to nothing unless you work long hours, have a community helping you, are heavily biased, passionate, or can add some other significant value to the information you consume and sort. But if you are an agressive marketer being able to sort through information so many different ways makes the job much more fun because it gives you so many options.
