We recently passed 500,000 posts on ZooChat - quite a bit milestone. Most webmaster communities which maintain lists of "big boards" set the minimum post count at 500,000 to be included in their list. I will note that on ZooChat, this post count includes photos which have been uploaded - every photo has an associated post with it that contains the description of the photo. Not every photo has a meaningful description, so one might argue that we don't really have 500,000 real posts ... but at least from a raw "how many rows are there in the 'posts' table in the database" count ... we're over 500,000. Next goal: 500,000 actual posts (currently 347,000).
Wow, 500,000 is a lot of posts. It appears that Nov and Dec 2012 were the #3 and #1 months for number of posts in the last three years, so is it fair to say that the site is getting steadily busier? Do you know who made the 500,000th post?
