You could use what NYT uses, that sometimes annoying function that opens a search when you click on any word on an article page. I think it’s from answers.com.

Try clicking a word in an article on this page to see what I mean:

http://www.nytimes.com/2008/12/22/business/media/22warner.html

When you click a word, you get a little [?] icon, and clicking that brings up a search for that word.

Here’s the JavaScript (I think):

You could use *something* like that to accomplish what you want to do. The post would not necessarily look like all links.
