CC @slandath - updating the https://jupyter.org/about website is another thing to do when the EC changes.

@jupyter/executive-council - this is a good chance to look at your card at https://jupyter.org/about#executive-council-members and tell us if you want any updates on the above info for yourself as well.

Closing since #836 does this better. Thanks @slandath!
