Unfortunately, this thread has turned into a debate about filters in general. That was not the direction I wished to take this discussion.
Almost every single thread goes off topic or takes an interesting twist at one point. Some threads went as far as having a totally different topic introduced after a while.
See the thread titled “Post to Post—-Not” started by BaalHabooze. Popa__bar__abba has a good comment there. (I don’t know how to bring the link here. )
