People use the argument what's to stan. They don't have comebacks and so on. That really is negligable to me. There will tend to be solo activities from at least one member. SNSD has been inactive for how long and we still get solo comebacks from Taeyeon, Tiffany, Jessica, and other members. Plus there tends to be enough material from disbanded groups to last. You can post old mvs, performances, solo status updates, fan meetups, clips from variety shows and so on.
edit: Plus as we use it on KS the word stan is really a meaningless word that people use to connect to other people on KS through groups they have in common. My version of a stan is different from
@RandAlThor version of a stan. I don't post updates on individual members of the groups I stan, but I don't view that as me being less of a fan than he is. Just a different expression of devotion.
