This is so crazy! I was just planning on making a thread about this very thing! Synchronicity!

In some ways, I don't think this is completely a hierarchy thing. I do like to see people like Benzeme, or Infundibulum post about something chemically related, and to confidence that they (most likely) know what they're talking about. So, it would be nice to see someone with a cactus or mushroom post about their related specialty.

As for the full member thing, currently the reward for full membership is the loss of your seedling, but I really like the idea of the seedling growing into a tree. I always thought the seedling was cute, so why should it just disappear?
