Good question. Most people read the paper on their own time, and we meet over lunch. The meetings themselves are just an hour, so it's not a massive time block. I've found that the people who show up are the ones who are genuinely curious and would be reading this stuff anyway (and sometimes just need a commitment/accountability to do it). Having a group gives them a reason to do it on a schedule.
That implies that you have a fixed time for lunch and also chat during lunch. I may be the minority but I prefer to eat when I'm hungry and focus on the food instead of chatting. And there is also allergies, as a celiac, I have big troubles eating together with others - they may accidently contaminate my food

How exactly are the meetings structured? I.e is someone leading discussions? Does each person go around and share thoughts? Etc
