Yes. I was just at a cancer biology conference with thousands of posters (multiple days). This year, it was also hybrid, where posters also had to uploaded to be viewable by virtual attendees. But these were still full posters, not a slide deck. However, physical posters were still there and much more useful than a digital equivalent would be.
When walking the isles with that many posters, you’re not just looking for ones that you flagged because of the title or abstract. You’re also looking for new work, or things that catch your eye. I stopped and talked to a person who’s poster I just happened to walk by because it had the words “Shannon Entropy” on it. Turned out, I learned something because of it.
