Hat tip to Mashable - I found the Zemanta plugin for WordPress, which is just astonishing. It suggests contextually relevant content from around the web for your blog, all in a useful little sidebar.
Let's say I'm blogging about Sallie Mae, my archrival. Just by putting those words in my post, their corporate logo and various content on the web appears in the sidebar. Or JP Morgan Chase. Or Citibank.
Add a couple more clicks, and you're adding blog posts, too. Got an Amazon book recommendation, like Made to Stick by the Heath brothers? Zemanta will let you build links with your affiliate ID with just a couple of clicks.
