Continuing from User public profiles in MVP - #20 by rodolphito, I think we need a mechanism to import tags or tag groups as sites, for cases like SO which are too large imo. SO is roughly the same size as the rest of SE combined, and it feels like the equivalent of having a “Religion” site and just throwing all of them in there indiscriminately. It could benefit from splitting at some level like “Java ecosystem” site, “.Net CLR ecosystem”, “Databases”, “Web dev”, etc.
