Because that's already what everyone does. And just posting every once in a while and hoping it catches on, that doesn't work for anyone, does it? That's how a community dies, as a community with a single poster isn't a community. They should keep posting to relevant spaces and look for people who might support them. Takes two to make three. Maybe grab some top posts to try to hit the front page. Post it in New Communities with catchy titles. etc. etc. There's lots of things they could still be doing if they really want it to take off, haha. I didn't make a single post on YSK besides the welcome post and some meta posts as needed, and was always clear from the start that I will let these spaces die if our first few members stopped posting.
