I commiserate with you on this. I miss my crochet and knitting communities from reddit, but I did make the severance anyway. I also don't use my Facebook account at all, so I don't have an online fiber arts community anywhere.
I belong to a small social knitting group, but I'm the most advanced knitter there, so I don't feel like I have any outlets for finding and appreciating master knitters other than YouTube. But I only turn to YouTube for tutorials/entertainment, not for a sense of community.
