Not to sound critical but it sort of does read as a spam-ish post.

It may have worked better as a more normal post and less of an advert. Like 'hello we are organising a (free?) talk about decentralised social media protocols at penn state...blah blah'.
A more conversational post or something.

Who knows maybe that would also be deleted lol.

But generally I think a lot of Nostr content on other platforms can come across as too spammy. (I think you have to imagine for eg if farcaster made that post, how would you read it? And put yourself in that skeptical headspace, cos that is often how it comes across).

I quite like the recent Reason video as a go-to for sharing. It's quite informative and doesn't come across as too much of a hard sell lol
