Not sure if this has been mentioned before, but you can give your text a nice boost of definition with the 'Film' plug-in which gives it a nice grunge feeling to it. It kind of reminds me of the scrambled picture you get when losing a connection to a TV channel.
First off, you can download the plug-in from over here.
So, open up your piece and write out your text (by my experience the effect you will try to achieve works best on white color). After you've done that, duplicate the layer. Apply the Film effect on the top layer. Calibrate the settings to your liking and render the effect. Next, click on the bottom layer and select everything but the text with the 'Magic Wand' ( ) tool. Keep your selection selected and click on the topmost layer and lastly, hit delete.
Here's an outcome on how the effect should look like.
