I'm looking at buying some kind of Twitter friend-adder/user account creation software, and one in particular (Mass Twitter Traffic) offered a puzzling "tip" for using Twitter. And for reference, I am not very familiar with Twitter yet. The tip was to only follow 50 people per account. But the limit is 2000 (until you reach 2000 people following you of course). Why would you want to limit your accounts to just 50?
