Guy Kawasaki's Twitter Strategy

I've followed Guy Kawasaki on Twitter for quite awhile and have been pondering his Twitter strategy for a bit.

Here's what he appears to be doing

(1) he has a massive Twitter following he's built through time
(2) he finds interesting stories across various blogs and websites online
(3) **he summarizes** the articles on his site (example is at Definitive guide to sticking to your resolutions - Holy Kaw!). Note: he doesn't actually write an immense article most of the time. Instead, he just summarizes another article someone else wrote and provides a link back to the orig article.
(4) his Twitter readers click the link in his Tweet, visit his webpage (Definitive guide to sticking to your resolutions - Holy Kaw!), see the summary, and possibly click through to the full story, browse around other pages of his site, or click on his ads.

Here's the thing I'm realizing

Guy is getting massive amounts of web traffic, thus getting massive amounts of exposure to ads on his site (revenue), without having to be a content generating machine. Instead, he's basically summarizing tons of content on his site and providing a link back to the original stories.

Applying this yourself

I think this type of strategy could be effective for building your own Twitter presence. It doesn't take much to summarize articles, and you could put CPA or some sort of ads on your blog to monetize it. I'm going to look into the time vs ROI of doing this in the next few days, but wanted to see if other warriors have done this.

*a better method Guy used to use*
I briefly met Guy Kawasaki at an event in San Diego in 2009. He had talked about how he actually showed other people's full content (i.e. someone elses full blog post) but did it within the "shell" of his own webpage. Basically, he would show someone elses full content but have his own banner ads across the top of the content to monetize it. This was done using objectivemarketer.com I believe. It was interesting but a bit controversial, BUT he doesn't appear to be doing this anymore. Instead, it looks like he's just summarizing content.

What are your thoughts on his strategy of summarizing?
