Many podcasts are willing to air promos for related sites (mostly podcasts, but not always), often for no cost or just for reciprocity.
Should we create a short audio promo for Judaism.SE and try to get it onto some Jewish podcasts and radio shows?
If so, would you like to draft a script for it? You can get some inspiration for verbiage from this discussion.
If so, which podcasts and radio shows should we target? Bonus points if you know someone working on them. Actually, we could target people working on such media even without a promo, just to get them to try the site and mention it themselves on their shows.
