As always, you can listen to it streaming here: http://www.oreimo-anime.com/radio/index.html
This time the girls talk about Valentine's Day, games, how to deal with being an otaku around family, and more Internet slang.
I didn't notice this before, but the Otaku Girls Gather is the name of the group Saori runs.
So we're more than halfway done with the shows. Woo.
