What constitutes an active user? Is a new lurker like myself counted or is there a threshold of minimum action needed to be counted?

That's really good to see. But it will be far more interesting to see what the numbers are a month and longer are from now. If they don't stick, it's pretty meaningless.

I created an account a while back and I'm back after receiving a warning from reddit for upvoting certain content. I was going through the communities looking for stuff to subscribe to and I was a bit surprised by the number of communities with a couple thousand users and the last post being half a month or more out.

I hope people's suggestions about making the instances and navigation more seamless is being taken seriously because there hasn't been much change there from what I'm seeing.

This is what happened when I joined obviously

I'm more of a lurker, but just recently joined also
