Come work on your side projects with other JS developers for a few hours. Get some help where you’re stuck and give out some help, when you can. There’ll be pizza and drinks to get you through.
If you don’t have a side project, build a Hacker News SPA in a new framework. There’ll more than likely be people looking for collaborators on their projects, or try your hand at some Open Source work.
If anyone wants to give a talk one month, don’t be hesitant to ask. It’s a great way to get started into teaching others.
