Now see, the thing is, a warm welcoming of spam is still more enticing to a newbie than the cold shoulder at cannibalistic supper.
...Yah? Yah.
Besides that, I mostly went to the intro section to raise my count to 200 for my avvie, and I took the time to personalize each welcome (unlike some intro spammers we know XP).
Now I have my avvie and I go out of habit and because I really do like welcoming the newbies.
A less-than-perfect reason to do something at first can be the beginning of a great reason later on.
