You are definitely on the right track. One of the jobs I assumed when I first joined was welcoming all the newbies. The bots were about the only ones who were doing this because at that time, there were no rewards for comments. It was when Dan noticed that no one (besides me and a few others) was commenting, that he realized that that was a big problem. Then things shifted and we got the ability to be paid for comments. I did a lot of welcoming in those early days. We need more people welcoming newbies, it's getting so crowded!!!
