Article about pros and cons of pen names?

I thought I had recently read a very good article about why pen names aren’t necessarily a great choice for today’s authors. I also thought it might even have been on Author Media. I planned to pass it on to a friend. But I can’t find it anywhere. I checked my other usual sources for author and publishing advice, and I’m not seeing it. Maybe I dreamed it? If you’ve run across anything that fits this description, please share a link. Thanks!
