I actually thought it'd hit my embarrassment squick, too. But there are a number of reasons I like it in spite of that. Portability! Definitely. No more printing out fanfiction and reading on the schoolbus like I did back in the midst of time at 13, when anyone could read over my shoulder. Two, I like being read to. It's fun to have a person reading me a story. Three, multitasking. It's hard to read fanfic on the screen while cleaning or cooking. And four, it's just a different experience from reading text. Just as I enjoy audiobooks, but find it completely different from reading a book in my hand, it's fun to see what a story is like in a different format. As for the embarrassment squick, I found that for a moment it was a little weird to hear someone Reading Porn Out Loud, but as the story progressed I stopped noticing the reader so much, or thinking about this person sitting there Reading Porn Out Loud, and the reader became a conduit. I'm sad that unfortunately I don't think I'll ever be a podficcer (I recently tried and found that my voice is too difficult to understand when recorded), but I'll continue to enjoy reading podfic for these reasons.
