You don't need to squint: Flickr Groups were a major part of the Flickr experience. E.g. Hardcore Street Photography (HCSP) had meetups and even published several books: https://www.flickr.com/groups/onthestreet/ https://www.flickr.com/groups/onthestreet/ And basically any hobby that had an aspect of photo documentation probably created a Flickr group. Trainspotters, of course. Vintage computers? Sure! https://www.flickr.com/groups/vintagecomputers/pool/ https://www.flickr.com/groups/vintagecomputers/pool/ These groups were better than anything Instagram has to offer because there were lengthy discussions and moderation tools. Even today, it's still impossible to search for a photo using a union of two tags on Instagram. It's a pity that Instagram has beat out Flickr, but it's also a testament that ease of UX matters and is critical in gaining and maintaining market share.
