I've been frustrated with Apple's treatment of text clippings; they seem neglected. For example, you can't select and copy the text when you view them in Finder. And with the release of 10.5, I was dismayed to see that Quick Look could not view text clippings either.
However, I stumbled across a plug-in for doing just that! All the credit goes to the original developer. It also supports picture clippings, though I haven't tested that.
[robg adds: A short history of copying from text clippings: Until 10.3, you couldn't do this at all. When 10.3 came out, you could copy from clippings -- but only the entire clipping. In 10.4, you could actually select some text from a clipping and copy it, even though you couldn't see exactly what was selected on-screen. In 10.5, though, we're back to the 10.3 behavior: Command-C will only copy the entire clipping, even if you first make an invisible selection.]
