SSRIs block the reuptake, or recycling of seratonin transmitters. It's difficult to understand, but it has something to do with keeping those receptors working. You only have a limited number of them, so making them start over again would be foolish. They just float around free so you can use them all the time.
Yeah, it doesn't even make sense to me, but maybe someone who's scientific can explain it better.
The bottom line is that it doesn't keep your brain from manufacturing seratonin.
The following came from the site you linked:
6. HOW SSRI ANTIDEPRESSANTS PROBABLY WORKIf too little serotonin (or noradrenaline) produces the symptoms of depression then correcting this should help to reduce the symptoms. One way of doing this is to block the reuptake (recycling) of transmitters. This is just what an SSRI antidepressant does. They block the reuptake of serotonin, so the next time an impulse comes along, there is more transmitter, a stronger message is passed, and activity in that part of the brain is increased.
