I'm just wondering if one of the moderators could give us some idea of how many posts are added in a day. I'm guessing there are thousands. Nobody actually sees more than the tip of the iceberg. For one thing, while you're sleeping people on the other side of the planet are busy on here. If you frequently click "recent topics" you'll see that they're constantly changing. Many are just a flash in the pan that you'll not catch unless you just happen to click at the right moment.
I imagine it as a rapidly flowing stream of ideas, thoughts, pictures and words, and all of us sort of "fish" out what we enjoy and toss back the rest.
Nice work, all who make it possible!
