Group suggestion: ~socialmedia
Hereby I suggest that there be a dedicated Tildes group for social media–related topics.
Current State
The (recent) number of topics tagged social media
exceeds the number of topics in several existing groups:
https://tildes.net/?tag=social_media
In addition, there are more topics without the social media
tag but with tags related to individual social media, e.g.,
https://tildes.net/?tag=reddit
https://tildes.net/?tag=facebook
https://tildes.net/?tag=twitter
These topics are quite scattered across the site (many of them are in ~tech, and some were moved to ~tech from places like ~talk and ~misc).
Why Not Just ~tech?
The topics are often focused on non-technical aspects of social media, and the mentioned moves from more general groups might suggest that social media are perceived as a general rather than a purely techn(olog)ical phenomenon. In addition, ~tech is already the biggest Tildes group.
Special Relevance
Tildes is itself a social medium site, and many of the above topics are thus specifically relevant for Tildes. For this reason, I suggest ~socialmedia as a top-level group rather than a subgroup (of ~tech, apparently).
Is there a way to take moves between groups into account?
For example,
https://tildes.net/~tech/bgb/r_piracy_receives_official_warning_from_reddit_legal_about_74_copyright_infringements
was moved from ~talk to ~tech according to the topic log.
Definitely, some numbers is better than no numbers at all. Whether, which, and to whom (built-in) statistical tools should be available is another interesting question.
My main suggestion is that a social media (sub)group is created. While I would prefer an independent top-level group now, a subgroup is still better than no group at all. Another reason why I prefer top-level is mirroring the top-level ~tildes. But your argument does make sense too. (The optimal number of the top-level groups is an interesting but different question.)
As for privacy,
https://tildes.net/?tag=privacy
this seems to be an extremely frequent tag, and the topics are overwhelmingly in ~tech (and if not, they seem to belong there anyway). It is quite interesting that while privacy is not a tech-only topic, nearly all of privacy-related issues today do necessarily involve technology—whereas social media are tech, but many social media–related issues extend well beyond tech.
Moreover, the topics of social media and privacy intersect, which can be eventually used to test the directed acyclic graph model (~socialmedia.privacy [or ~tech.socialmedia.privacy] and ~tech.privacy.socialmedia should point to the same place).
This is a super old conversation about the hierarchy structure but it's relevant and I think you might enjoy reading it:
