It is actually more than that. I am following some 150 people and it is very rare that people tweet about what they are doing. When i started using twitter, i was skeptical that it would be of any value. But slowly i realize that it is much more powerful than i thought. It is like speaking on a stage where your followers are listening to you always.
By just putting in 10 or 15 mins of your day, you will be able to generate a lot of value from your twitter account. It is like a brand, better you tweet, more followers you have (how you utilize them depends on you).
Giving you an example, I have around 225 followers, so whenever i tweet a link, i get around 50 views. There are people with more followers like 1000 who i am assuming get around 250 views for every link they post. Mike Arrington has close to 25k - 30k followers, i am pretty much sure he get lot of traffic from twitter and he is also socializing with his users.
I have a Twitter account with over 10,000 followers (not my personal account to which I only have 1500 :)) and you're guaranteed about 80-100 clicks within the first few minutes of linking to something (yes, I've used a tracker). Typically, it sees about 250 clicks overall (within 24 hours) with 500 being a record (back when it had about 8000 followers).
