... and if you post in a thread your "Bump" isn't as effective as if you hadn't posted to begin with.
I don't get what you mean here. Let's test it: on the
Announcements (Altcoins) board,
this thread doesn't show on the first page. After
I made a post, it was the 17th topic on the first page of the board.
I'd say my "post bump" was pretty effective.
In the ANN thread for bumping IIRC I had to bump about thirty to fifty threads before my bump power was totally exhausted
That's for "Superbumps", not for "posting bumps" (those don't get exhausted).
I'd be interested to see how often Superbumps are used. This doesn't need to be naming and shaming, but in general. I've used it once in a while, but only used a fraction of my "bumping potential".
