Agreed! We need demos, well prepared presentations, real stories, tutorials and walkthroughs (e.g. Craig Raw was amazing in Miami with Sparrow), new technology proposals (like Ark from Burak - presentation well done).

Couple other ideas

• If there's food or drinks offered at the venue, provide sponsored sats-back (e.g. if the person pays, they get 10% or even 50% back in sats over lightning). That gets the people to install wallet, because people like free stuff and then they can spend the next day.
• No stupid panels with couch people (one exception that was actually great in Miami was Matt Odell's one - they answered questions from public really well)
• Create smaller groups and go for lunch outside of the venue to a place that accepts bitcoin (find on btcmap.org)
• At the entrance everyone should get a small booklet with tutorials (get first LN wallet, using POS in business, self custody with hardware wallet)
• invite folks in the community to do reporting on the event (like Marce came from Costa Rica and with others did great random interviews and reporting on Nostr)
• everyone should bring a "gift". A small thing they give or provide to others. E.g. I had a flashed hotel NFC key card with lnurlw and I was giving away sats to people I chatted with with just a tap. It was a great success and conversation starter.
