If you over think your post too much, you'll never get around to actually making a post while your point is still relative to the conversation.
Like when hanging out with friends, sometimes you just gotta blurt out what you want to say or the moment passes. You might have something that could be really funny, but if you keep over thinking it, someone could beat you to the joke.
Trust me, I've spent the last 10 days watching so many opportunity for jokes just pass me by while I wait for Pail to approve my post. Even some of the jokes I did make you will probably never see, since they were deleted without approval. Some of them got through, but they were so many post ago that you would have to search back through some threads to find them.
