I believe this is a really important discussion. My personal wishlist for the Café—along with any other reading groups and meetings, etc.—would be that every event is made available in video and audio format, along with a transcript, and that they are archived in a way that makes them discoverable later on (for example, by including keywords and notes of what was discussed, which could be searched).
Some of the architecture for this is already being developed with the Cosmos Cloud and Cosmos.Earth initiatives. Some of it can be done with tools already available (e.g. tags) on the forum
Our websites in general could use an accessibility audit (@kayla given some attention to this, but it is a big job that will require a lot more attention).
I personally orient better to audio than to video, but I appreciate that some ‘information’ simply cannot be adequately transmitted or exchanged outside of the context of full televisual presence and participation.
Since these are public events, which are not meant to be insular or only of personal relevance, but also have some ripple (or larger) effects on a wider consciousness and culture, I do believe we should be mindful a diverse range of abilities in our audience…while being mindful, as well, that we are not merely (or primarily) performing for an external audience, but are fully engaging with whomever is present in real time and (virtual) space, making the event happen.
That said, it seems a small thing we can do is to be mindful of our asynchronous audience when introducing visual elements. We could also be more conscientous when referencing names, books, or websites that non-intensive forum participants (or even the regulars!) may not pick up on. These latter, of course, could make their way into the episode notes.
