@silverpill hey, thanks for sharing the link!
Interledger Foundation is also a W3C member, and can join the Working Group directly. They don't need to make this grant to participate in ActivityPub standards.
The grant is for four subprojects:
1. Fediverse sustainability. What are the economic, psychological and emotional pressures on instance operators and other infrastructure providers? How can we support them?
2. Creator economy. What social, organizational, and technical infrastructure do content creators depend on? What are we missing on the Fediverse?
If you have a fediverse account, you can quote this note from your own instance. Search https://cosocial.ca/users/evan/statuses/116017240784182814 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
