Thanks for the input, and I apologize that this is on a Saturday. Given the design and interactions we're trying to create, this is what happens to work for both engineers and founders at the moment.
A lot of people have ideas on remote/online events, and I love that idea. I'll see what we can do there. We're also experimenting with other formats, including evening mixers.
Lastly, if you're interested but the date is prohibitive, we'll work to get the presentations online in a format that works for engineers who are unable to make it over the weekend.
