My top two reasons are:
- Finding out what someone does if their booth messaging looks like it solves a problem I have
- Getting a demo if I'm a bit more certain that it's a good match
My biggest blocker is booths that use some investor-facing phrase that means nothing to me as a practitioner. See "Agentic Observability" and most words to do with streamlining/productivity/boosting/leveling up, etc.
