Comment to someone you haven't ever interacted with before or introduce yourself to someone you've briefly interacted with and friend/follow them.
Oh boy, I've been friending and following like crazy thus far into January. One of the things about the fandom diaspora that drives me nuts is that people will have different handles across different platforms, which makes it challenging to know who is who, and whether I want to follow them.
I say this with my handle is the same across all platforms, but I don't mean it in a judgey way. Just a -- my brain struggles to connect several variations on an identity with one another.
So all this posting and linking in snowflake_challenge has given me a super useful tool to run into people here that I haven't really followed since the LJ days. Most excellent.
