Seeing loads of 'you should try Linux! It's easy! All you need to do is (bunch of scary jargon)' and not much 'I'll be in (cafe/workshop/community space) in (town/city) on (date/time), bring your laptop and a USB stick and I'll help you get started on Linux'.

For a place that has such a HUGE Linux and FOSS culture, the Fedi would be a great place to organise a movement like this. I propose #GetLinuxed if someone wants to set up and organise this :P
