I've had relative success reaching out to people on the forums but I think the trick is to not just post a link and hope for the best but rather do it within a conversation of sorts.
I made a topic called Any tips for writing basic judiciary laws in fantasy settings? and it attracted a lot of cool, likeminded people that got along really well. We hade some really good conversations and I for one learned a lot from them.
Most of them had their own comics and most of them I started reading : >
AND SOME OF THEM EVEN STARTED READING MINE! : D
So I feel it's more a matter of showing that you care, because if you care than others will care <3
