Encourage Diversity: For people with disabilities
Serving the disabled is indeed important. Are you talking about a formal committee or an ad hoc group of volunteers. If the latter, I'd encourage you to form a Task force. You can do a lot of preliminary research, and you could easily formalize later.
Iām rather thinking about a formal committee. We started some kind of taskforce already, the Wikimedia Accessibility Initiative, and there always have been local initiatives. But volunteers can only do so much. Accessibility needs to be incorporated in the official strategy, we need people dedicated to this full-time.
I'm glad there's a committee already; it's an excellent first step, and I'm looking forward to seeing what emerges from it.
I hope that this group will think at a movement-level. In other words, don't just think about what the Wikimedia Foundation can do to improve accessibility. Think about what partners the community at large could do.
