All kinds of people from every different profession have picked up the electronic pen and become citizen journalists. It's up to you to find them (and all their friends) so you can recruit them. Blogs can reveal names of candidates, give you competitive intelligence about companies, products and tools people they like and work with, reveal industry trends, and help you discover who folks hang out with online (peers and co-workers).  Check out this example (type the following search string into www.google.com):

Java Websphere education (blog | blogs) (comments | rss | feed | archives | posted | tags | trackback) ~cv -job -jobs -send -submit -you

Why it works is because there are some very common elements in blogs. For example, most blog platforms allow readers to leave "comments" and publish RSS feeds of the content of the blog. If we find pages with a comments section, and an RSS feed and perhaps links to pages such as archives of posts, and "trackbacks" then we probably have found a blog! Add to that the fact that you are searching for words similar to CV which of course include resume and vitae, and you have a search for resumes posted on peoples' blogs! The - terms eliminate garbage results like job postings, for example.

All you have to do is change the Java and Websphere to words like Nurse and ER for example, and you have a similar search for nurse resumes!
