THREAD TANGENT:
It's not aimed at you, Kelly, don't worry! As soon as anyone else reaches a 4-digit post count you will see they will automatically join the same ranks. Post count isn't deleted, modified, or inaccessible to those who are interested, for example
right here and in anyone's profile.
It comes from a personal feeling that while post count is important to some extent, (I'll certainly listen more carefully to someone with a couple hundred or a couple thousand posts compared to someone who joined 2 days back and has 3 posts), once people reach a certain threshold of posting the perceived difference between them and other people who have reached that same value can't be relied upon and is more a distraction than anything meaningful. More simply, someone with 5,000 posts doesn't necessarily have anything more useful to say than someone with 2,000 posts. They very well may, but not because of their post count differences. Both of those posters have reached a level that people can recognize as being significant.
So that's why it says that. If you don't like just that phrase ("A lot"), and instead have a better suggestion "> 1000", "zillions", "a whole buttload", let me know and if I agree I'll change it for everyone.
