Firstly, I'd like to state that the current mod team is excellent. Specifically because it's a great mixture of traits; Yisela the big empathetic heart, JohnB the peacemaker and AlanG the wise.
Next I'd like to empathise for a moment and wonder how it would feel to have worked so hard to bring this site to graduation and then only moderate for a very short period once graduated?
This site has been evolving constantly since before I joined and I think Yisela and JohnB have actively adapted to it and nurtured it along the way. I don't think any normal user is geared up to support this site as well as they do without a fair bit of practice. Therefore it'd be like spending valuable time training someone to do a specific task and then firing them.
I think it would be far better for the team to grow by one or two people. It should also be noted that since graduating, question cleanups appear to be taking slightly longer to me, and I think that's due to the large shift in rep required for privileges, so there are far less users with higher level privileges, increasing the strain on the mods and 10k+'s
Is there a specific reason, other than our low question-per-day-rate, why we can't have more than 3 mods?
Sometimes there are complex matters here that could benefit from additional minds, things that can't be quantified in statistics.
It would be good if our mods could share their thoughts on whether it would've been good to have additional full mod support or if it can be handled by 3 people, taking into account the likely growth of this site now.
