Ravelry is an amazing site for fiber artists (knitting, crochet, spinning, weaving etc.). It has an encyclopedic database of patterns, yarns, and projects allowing you to scope out your next project, and find out if the pattern does what it says it does, needs a specific yarn, or looks really cool with a new modification. They have a unique community structure that allows people to form their own little sub-communities to connect with folks, and I have met some of the most lovely supportive people this way. There was a time I would have lost Everything I owned, if not for a generous member I met through Ravelry offering to hold my things while I was homeless.
The site designers have always been huge on inclusivity and making people feel welcome, and have lately taken a stance on mentions of Trump reflecting that. Overall they have had a hands-off policy with very few overarching limits, but they feel, and I agree, that this was necessary to maintain the safe community they have built. Sadly, they're dealing with some insane backlash.

TLDR: Ravelry is literally the best social network I have ever interacted with, in terms of User Interface, Community, and Functionality--AND it has a phenomenal database to boot!
