I don't have enough karma yet to post this as an original post but, for those who remember Grognor:
1 - https://grognor.github.io/ A memorial site where people can submit tributes for publication and otherwise 'remember' him.
2 - https://www.youcaring.com/floridaexoticbirdsanctuary-955648 A fundraiser in honor of him.
He passed sometime in June and I know that he was a valued member of LessWrong and cared a lot about the communities he inhabited.
Grognor did a good job collecting his own data. I don't have access to his alt twitter account, as it is a private account. But maybe someone else who does can help if the demand arises.
