Up until this evening, I've largely ignored internet advertising in all it's forms.  I haven't blocked it, I haven't even thought about it because in most cases it was never intrusive nor bothersome.

This evening I made the choice to begin blocking ads.  I started by downloading the Adblock extension for firefox and then configuring it to block the IntelliTXT ads.  If you haven't seen these, they are the ads that randomly double-underline words and pop-up a window when you roll over that word.
