Once a community gets large & diverse enough that it starts wondering about its own composition, it enters a phase in which it has to start to examine a lot of unspoken conventions. Since Clay Shirky wrote about this phenomenon so well, I propose we call this stage "Shirky Completeness".

As far as I'm concerned, you've built stuff and want to build more stuff; you're polite and thoughtful. Enough for me. Welcome. :)
