Just wanted to share a post I helped write on the queer women's website Autostraddle: Period 101: Toxic Shock Station Stomps Out the Tampon Industrial Complex.
Hope you enjoy it! :) (I'm Dina in the post, BTW, which should be fairly obvious if you read it... ;) )
ETA: Also, I should point out this comment - she's talking about you folks here! :D I can't take credit for menstrual_cups on my own - it wouldn't be half as amazing without the people who post here. Thanks for being part of/contributing to such an awesome resource.
