Thanks for the listen, it is not often I am accused of keeping things on track;-)
I’ve though about this a wee bit. Doing the whole thing via the indieweb would be beautiful but it raises the barrier for participation very high. Setting up WordPress for indieweb is certainly doable but the number of folk interested in WordPress and education that would do this would be low. Given the notion of accessibility I think this is more something to aim for long term?
I had though of the idea of running the whole thing on p2, I’ve set up a couple of short term p2 blogs for Education Scotland to go with public events. You can set p2 to allow subscribers to post and set a widget to allow self registration. In our set up this registration was limited to Glow Scotland users. This of course loses the indieweb bit. Unfortunately p2 is pretty horrible on mobile.
I hope you get a proposal together, it would be great to have an indieWeb presence virtually at the conference. I expect you would post your presentation tweets via your site. I did consider that last time when I presented but was worried about timing and appearance on twitter which I’ve not really got my head round.
