Let me explain to you how this works. I will use small words and try to avoid any abstract concepts.
The FR board keeps a running tally of posts. Many of the posts on the board, depending on the time of day, may be overlooked by interested parties. In addition, a large number of Freepers have other obligations which prevent them from monitoring the board on a minute to minute basis.
In addition, many Freepers have a intellectual life, and instead of having a slavish devotion to an ideology or totem...like many Bushbots do, for example...actually read other sources for news and opinion and use their critical reasoning facilities to debunk outlandish claims made by Bushbots such as Bush is a conservative, or that under Bush, conservative ideologies like smaller government, less federal spending and regulation, etc. are in fact, being implemented. Satirical comments like mine are often used to illustrate the point. (Dear me, is satirical too big a word for you?)
On occassion, the Homo Sapiens on the board who find items of interest in the news and wish to call them to attention have the courtesy of using something called the "Search" function to see if another Homo Sapien has already found and posted the item of intellectual interest, so as to avoid duplication. The Homo Sapiens understand that timeless messages and truths, such as, oh, say, the Declaration of Independence and the Pledge of Allegience, bear repeating.
Unfortunately, I see that there are still some more primitive human species like Neanderthals on the board who do not understand such concepts.
Any questions?
