For those planning on being in Washington Heights for Shavuot, I'll be speaking in Mt. Sinai on Shabbat between Minha and Maariv on the topic of "Segulot, Simmanim, and Superstition in Mahshevet Hazal." As you might expect, the subject does not lend itself to a comprehensive treatement in a 1 hour shiur so I will be covering some of the halakhic and hashkafic sugyot identifying ambiguities and contradictions.
Depending on how it goes I may write it up afterwards, otherwise I can post the mekorot if there is interest.
UPDATE:I'll also be at the Bridge Shul at around 1:00 AM.
