From what little I know regarding 80,000 hours it actually is worthwhile and one could make a good argument for being worthwhile to advertise or just discuss here. It's just that it strongly pattern matched to other advertising, like when LG came to a technology forum I frequented so they could tell us about their fantastic products for cheap! I wouldn't be averse to a different discussion talking about how it helps people achieve optimal philanthropy. Effective altruism is something I (and I'd wager a lot of people on this forum) find interesting.

Edit: Just one quick question, why is 80,000 hours called 80,000 hours? It's a striking name, but a cursory read of the FAQ didn't explain.
