Usenet Marketing?

[gegenschein.livejournal.com]

Hi everyone, sorry that this is a text only post, but I was wondering if anyone has marketed their products on Usenet groups, and if so, which ones have you been successful with? I'm looking to expand my store's marketing range from LJ and don't know much about finding good usenet groups. Hopefully someone can help me. :)
