@Alistair Shepherd Apologies for the confusion! We originally had the date on events.indieweb.org as this Tuesday, but we had a bonus HWC last week which I think confused the dates. The events.indieweb.org site now shows the correct date: the 16th.
I will be there next week too! I haven't been doing much writing recently, so I hope next week I can write and publish something.
I'm excited to hear about what you wrote this week @Alistair Shepherd 😃
