Te real point is that it is a discussion thread, and not a discussion post. I don't understand why the poster has to assume that all readers have such a limited memory capability. I would assume that the majority of the serious members here are of above average intelligence, and are quite capable of following a conversation.

Of course, if the thread is so spam laden that the poster feels that he has to isolate the relevant posts, then we will need to address the spam pollution as a priority. This has already been highlighted in this thread, but until that happens, it would be great if members could not amplify the problem by quote abuse.

Reading a thread when looking for meritable posts is a bit like driving down a dual carriageway road. The vehicle in the slow lane ( normal text ) doesn't slow you down too much, and even the rubbish spam can be passed easily, much as you would pass a bicycle. Finding a block of quotes or a large image is similar to being blocked by a slow moving truck in the fast lane, you have to get it out of the way before you can move on. If a road always contains slow moving traffic, then you choose a different road in future ( ignore the board ).
