I confess to a blunder on my part: I did indeed open this thread with the statement "This new rule, approved by the moderators, will not affect many of you." That was inaccurate. It should have been something like "This new restriction... will only apply to a few of you". The rule affects everybody, in that it changes the makeup of the forum. Before, it was possible for a couple of participants, or even just one, to take over the entire front page and push everyone else off. During the mods' discussion, I documented a case where a post was pushed out to page 2 in less than an hour, and that by one individual. As we can see in this thread, some had no problem with this situation, but others resented it.
As I remarked below, the present situation is not exactly cruel to megaposters, allowing 16 posts a day. And those who disliked the earlier practice feel some relief.
I regret that I have to re-express my bewilderment at the charge that "too much math is involved." When you post, you are returned to the front page of the forum and can see the latest posts (the default number of them is 20), and you can count them: if you have made eight posts, stop posting. Is that too complex to implement?
You can post again 12 hours later. If you don't bother to remember the time of your earlier posts, you can determine it by opening your last post and reading the timestamp at the top: if it's more than 12 hours ago, post away. If not, wait. Is that too burdensome?
