So what if I have 3 times as many posts as you? It just means I've been here longer. Refer to the comment in Van's signature about not confusing word count with content. Post count does not neccessarily have a relationship to quality of posts...
Now, now, now, if I post the same comment each time it alleviates the need for me to have to think up something new. Much easier for me. That is why everyone generally gets a generic welcome...
