Another option is pre-recording your presentations. Shoot for a 15 minute presentation, followed by questions and conversation. Think a dev recording their screen, showing the work and talking over what they're doing, mixed with a few powerpoint slides.

This gets over the hump of public speaking, creates an artifact that can be sent out as a follow up, and gets to the goal of having shared knowledge of a topic and a sense of community outside of normal silos.
