Some interesting ideas to watch here.

I remember a Twitter app service that was built around Twitter lists that I was an early user of, but I'm not able to find it now. I'm not sure if it's even still around after Twitter killed off a lot of their API access years ago.

Hey Twitter,

I love that you chose to show support for Lists by sharing the list of Blue publishers, this way. This is a decision I want to celebrate!

However, this hyperlink isn’t particularly useful in that the user has no ability to actually follow the list. Aside from manually bookmarking it on a browser (since you can’t if you let the deeplink open the native app,) there is no way to save it!

Not comprehensive of all registrants or participants, but here's the start of a Twitter list of people who participated for those interested:

Do let me know if you've been missed or would like to be added.

I've started curating a Twitter list of the folks involved in shaping the 2019 Horizon Report. Visit the list and let me know who is missing.
