Grammar Girl

    Grammar Girl  is one of my favorite web sites for grammar.  It's run by a woman named Mignon Fogarty.  She does a great job of responding to real grammar issues and coming up with responses to people's questions.  She has a lot of articles, but she does some great podcasts as well.
     Here's a great podcast on a common grammar issue, affect vs. effect.    Ms. Fogarty does a nice job using a really simple illustration and pneumonic to get her point across.  She includes a voicemail in the beginning of the podcast to identify the problem.  The whole podcast is a manageable 5 minutes.
     There's a defined goal here, a simple and clear message, all in a mangeable format.
