If you don’t mind, I have a few questions/recommendations for you:
Are you someone with a many connections, or are you planning to just cold-call a bunch of notable people and hope for the best?
Where are you planning on hosting the AMAs themselves? On !amarequests, or on !askmeanything? (If the latter, you might want to coordinate with the current mod, @frankyboi)
What is your plan for promoting the AMAs (on Lemmy or elsewhere), and collecting questions ahead of time? I think both of these would be an important kickstart for the AMAs, and help ensure their success. For example, a few posts like “Notable celebrity John Smith will be answering questions on August 1st from 11:00 to 13:00 UTC, post your questions for him here” in the weeks/days leading up to the AMA might be a good idea.
Thanks again for taking on this project; looking forward to seeing what comes of it!
