I will not repeat too much about the community, but I like the hackathons they compete in. It might not speak directly to the investor, but it does show commitment to continuously improve. With price moneys to be won I am sure those hackers are motivated to breach through - yet none did since 2020.
Filecoin has a rather different approach to their community with WeChat, Slack, and Discord (mainly used for questions about their protocol) as main communication platforms.
Their telegram is nearly dead, and they are not even showing it anymore on their website. I was once in it. But it never was that alive anyways, if I remember correctly.
You can see what Filecoin is up to on Slack among 23,536 others. They chat there too. WeChat is for project updates and announcements.
Twitter has over 552,000 followers. That is a lot. 6,531 Tweets show they actively use Twitter for their announcements. Scrolling through the tweets, I find retweets with an average of only 12,000 views, but their main tweets get over 250k and some over 1,2m views. Considering their followers, you can conclude they have a very high response rate, with many retweeting as the views exceeded their followers by the 1,2m one.
Forum leads to their Github, which I don't have much to say about as it's the same brief info as any project has. To provide some numbers: 446 stars, 106, and 170 forks.
Surprisingly, their Discord is allocated to their IPFS, which allows peers to transfer data files between each other. A channel solely for the IPFS protocol. Show Less
