I was very confused by your usage of the word "poster" and "poster session". I had to go look up the meaning of "Poster Session". I've literally never heard the term used in relation to tech conferences in decades of geekery. Maybe I'm a weird edge case, but I doubt it. If you're interested in this being used for Non-academic / scientific presentations I'd suggest different wording.

for the other geeks who don't know what's going on with this "poster" stuff.
