I've said this several times both here and at the other place, but it seems to me there's a big opportunity these days for any particular community posts to be randomly seen on ALL, which obviously has a lot less likelihood at Reddit. As the FV grows, that may be less of a possibility, so jumping on it now seems like a good idea.
So currently, just finding a little bit of good visual content (usually accompanied by a link and or mini-review) and posting once on a near-daily basis seems to keep snagging users without having to do anything else.
I also try to maintain a community index and major keyword searches to make it easier for users to find stuff that might interest them. After nine months of such regular work, there's now a whole bunch of decent content for users from any other platform to dive in to and enjoy for many hours, or longer.
I hope to keep adding content (particular the original content, such as mini-articles & reviews) such that it's going to be harder and harder for the internet to ignore our community. Of course eventually, I plan on flaming out in a supernova of resentment and hurt feelings, deleting everything and erasing all my backups.
