Another good one!
In a way, a previous version of me already got this, back in the brony days, where the panel I did about how MLP:FiM helped me get sober got me mentioned in a washington post article, albeit with now outdated pronouns and my old alias, cadejo Jones. The 5 or so times I ran that panel apparently helped a lot of people and to this day I can't believe any of it happened.
That being said, I have some dream ones in mind!
Running—keeping it in the realm of the feasible but not practical: I have wanted for a number of years now to do "Taskmaster but it's the Korps" where we mimic the famed british TV show, but Karen (the one who created the universe) takes Greg Davies' role as the taskmaster, I fill in for little Alex Horne, and a few of the notable artist and writer personalities are the competitors. In theory, it would be possible to do this, but the logistics of both shooting and editing the video bits, as well as getting everybody to the same con at the same time, are financially and timewise beyond what I'm capable of.
Running, feasible—if there were ever a cohost convention, running a panel with other @making-up-mech-pilots writers would be a ton of fun!
Attending, feasible—depends on the convention. Is it for writers? Furries? Queer pride? Anime? Video Games? Tabletop? There's so many people I'd love to see talk! Also, big fan of game show schtick, always a winner.
Attending, complete fever dream: Jeff Vandermeer, Daniel Armbruster, Janelle Monaé and Trent Reznor all in the same place and I'm the only person in the audience and they spend the whole panel telling me I make good songs and I write really well and that I'm the sexiest NB woman they've ever seen and that I do inspire people and they somehow teach me how not to feel like I've never had a positive influence on anybody, that no one actually likes my art, that I'm not actually good at anything and that I'm and that I'm going to die alone in some terrible way. Then the panel ends with Trent giving me a signed copy of the Definitive Edition of Year Zero, which is also his way of saying that Nine Inch Nails is finally releasing it and then Danny buys a garbage plate afterwards.
