EthHub

Started 3-1-2019, before then it was known as Block by Block. Got discontinued (9-12-2022).
Website focused on Ethereum and its ecosystem.
They also had a EthHub Weekly newsletter curated by Anthony Sassano (@sassal0x) and Eric Conner (@econoar). Chaz Schmidt is also a core contributor of EthHub "before they even went live".
Got a grant in the first round and received the highest amount in terms of a Gitcoin Grant CLR bonus (the third round), earning $16,209 from the matching pool alone with a total of $21,006 in funding across 131 unique contributors.
Had another grand in the 4th round where it became the 3rd top grant.
