Hi! I'm seeing very different opinions about Web 2.0s as tier 1s. Some people like to put just one 300-400 word article on each Web 2.0, while others put 3-4 500-word articles on each of their tier 1s. Obviously the benefit of the first option is that you can have far more tier 1s for less money, but do you think this looks suspicious to Google? How many articles do you put on each of your tier 1s? Is it working for you?
