I don't know of a single resource, but I would search for "X [reading group OR journal club]".

Also, many academic associations, like ACM, have Special Interest Groups (SIG). Some SIGs have journal clubs but you might need to become a member or ask someone to add you to their Slack, Discord, etc.

Are there any specific topics that interest you?

thanks, this helps. i've tried different search terms with little success (descriptors for resource-based independent learning in groups are hard to refine). i'm retired so my professional affiliations have lapsed. and, with the freedom to pursue my interests, the possible topics are all over the place. but i'll look for some SIGs that might work (cultivating Australian native plants, tiny compiler design, etc).
