As far as generating more content/posts/activity: perhaps we could start some sort of special weekly discussion thread series? Maybe they could focus on aspects of things such as hobby ethics, hobby history, applying things they've learned caring for one species to another, etc. Alternatively, we could start holding some sort of weekly or weekly-ish "book club" or "podcast club" where people could discuss new herp literature or podcast episodes. I feel like Reddit groups have weekly "mega-threads" like this that are fairly active; maybe something similar could work here?
Do it! I can supply tons of media type sources. Podcasts, YouTube channels, etc. If you want to talk about this stuff, start the discussion!
I can make a new forum/section for this type of discussion if it is warranted.
