Old fandom—in the context of this article, fandom from before the rise of microblogging platforms like Tumblr and Twitter—was a very different place by virtue of being hosted on journaling platforms like LiveJournal or individual domains like GeoCities. The structure of those sites was more friendly toward written posts and long, individual discussions in comment threads, as well as communities keeping to their own and not having to see content from other parts of the site unless the user crossposted or linked to them. The average age skewed a lot older, with users on LiveJournal talking about families and jobs alongside their fan works, and younger users often either lied about their age or said nothing at all.
