Historically, there is a precedent of fandom having lost chunks of history, works that they care about, and contact with fellow fans as communities come and go. As Dreamwidth is openly fandom-friendly, in fact having been developed in response to the issues that drove fandom from Livejournal, it stands to reason that this is a much safer space to back things up to.
Currently, a lot of fandom communities are based on Tumblr, which is going under a period of change that may or may not lead to another fandom exodus. The Mod (kittenfair ) has run a fairly successful FF7 hub on Tumblr, also called FF7Central, to help foster fandom connections, and that is also why this community has been created.
Please note, I do not plan for this blog to be a replacement for the Tumblr blog FF7Central at this time. The purpose for this blog is simply to make sure fans can continue to find one another, especially in the event of another platform shakeup.
As I happen to be very inexperienced with Dreamwidth, this is going to be a slow, and rather rough process, but I encourage everyone to take advantage of this space to make sure connections are not lost.
I honestly hope this is an unnecessary measure, but better to be safe than sorry.
