Apart from the media attention that it’s been getting for the last year or two, there are some other telltale signs that Twitter is here to stay. The most important one is, of course, that hackers find it an interesting target. The worms that were released so far were merely a test; I have no doubts that there are more security issues, and that more advanced attacks are already being prepared, or maybe even in use. But there are a couple of other things that caught my attention this week:

The first one is, of course, the fact that @Oprah has started twittering. There have been speculations about this for a while, but this time it’s true. And it looks like people are more interested in hearing what Oprah is up to (“going on the air right now”) than in CNN’s breaking news; the graph below shows the follower counts for both of them.

The second sign Twitter is getting more mature as a platform it that it now has it’s own official O’Reilly book! I never imagined anybody writing a book of over 200 pages about a website that limits content to 140 characters or less; but Tim O’Reilly and Sarah Milstein managed to do so. “The Twitter Book” is now available as a PDF version. Apparently the book will help you to “Connect with colleagues, customers, family, and friends”. Clicking on the image below will take you to a more detailed description:


And the third sign was the amount of work my favorite web analytics package, Clicky, has spent integrating Twitter support into their normal statistics. They already offered statistics on the amount of followers your Twitter account has, but this week they added a complete monitoring solution that allows you to track certain keywords and tweets linking to your website nearly real-time.


Meanwhile, we’re still left wondering how Twitter will generate any revenue. It seems as though a new company finds a way to make money either by using Twitter, providing additional services or using the information in tweets every day, but everything stays quiet on Twitters’s side.
