Yes! These cults are awesome places and would be even better with LOADS of activity. I'm a fan of having a place specifically dedicated to discussion between those committed to the medium, and it really helps spread knowledge when the focus is on just that one idea.
For the record, here are the cults:
NS Journalist Network
I'm going to make a push to get the NS Photographers cult more active. We've sort of fallen behind over the winter, but there's been a huge increase in Photo discussion here in M&A that I think would be great if it was also active there.
