Whenever we contact a friend, one of the first questions we naturally ask is, "What's new with you?" If we have spoken to him recently, the answer may be short and simple. On the other hand, if it has been a while since we have visited, there may be much to catch up on. When we refer to website traffic as 'visitors', it is because this same principle of updating applies. The longer someone has been away from your site, the more he should find to explore when he returns.
