Sorry for the wait sir. May I take your order? Yes please, I'll start with a top-o-the-power-curve appetizer, and have the Long Tail for my main course. Not familiar with the "Long Tail"? I read about it for the first time in Wired. It's been bl... [Read More]

That's Fascinating stuff to a numbers geek (like me) -- I would hope you include it in the book.

Of course, the more math, the less copies you will sell.

Whaich raises a question: Which part of the fat head/long tail do you hope the book occupies?


Very interesting stuff. However, regarding this stat:

"Loosely speaking, if you divide the number of queries by 4, you'll get the frequency of the most popular query..."

My research shows that 4 is much too small of a constant to characterize the Search Head. That is to say, the head is not nearly that large - rather, you would need to divide the total queries by a number like 100 to 400 to get the frequency of the most popular query.

I would be curious to see where the stat came from.


For the best on the long tail, Zipf, etc,
Try reading Mandelbrot and Taleb:

Well, I'd like to put a good bit of math into the book and accept my inevitable place down the tail. But my publisher, whose money is paying the rent, would rather that I not. At the moment, there is exactly one equation in the book (unsurprisingly, y=ax^k), but we'll see if that survives the editing.

Funny, I just wrote a post on this exact topic:

"Loosely speaking, if you divide the number of queries by 4, you'll get the frequency of the most popular query."

This says that in a Zipfian distribution, the top bin gets 25% of the total. As I detail in my post, the percentage of the total in the top bin depends upon the number of bins, assuming that the distribution follows an exact inverse power law. According to this reasoning, if the top query gets 25% of the total queries, there were less than 100 queries!

Of course, in fitting real data to a power law all kinds of offsets, etc. are swept under the rug, so this isn't really a fair thing to say -- but it is an interesting topic in general. You can find more on similar long tail / power law stuff here, here, and here.


Doesn't have a lot to do with the Tail, but dr. Watson: I turn it off. On all workstations. People don't get it, or get annoyed. They are much happier when the application just crashes and they can restart it.


I came here from out-of-context. Frequency of *what*, measured in units of what, according to whom?

Among all the erectile dysfunction pills available in the market, it is levitra that has carved out a niche name for itself and levitra prescription has become much sought after for the impotency afflicted patients. The chief factor responsible for the tremendous popularity of levitra is that this medication to treat erectile dysfunction has shown successful results in treating impotency in men with health risks like hypertension, diabetes and prostate surgery and as such you should opt for levitra prescription online instantly. Bear in mind that levitra without prescription would not be able to show off the necessary results as levitra is a prescription-based drug only and should be taken only according to the instructions of the doctor.

Jeff Paul Internet Business

I find internet marketing the same as marketing a product in the real world. In real marketing one really has to go through different means to promote a brand and product. Same tasks are applied in internet marketing but this can also be done at the comfort of one’s bedroom.

wii spiele

Why don’t they just create an “archive” of less popular games? God forbid they be a little creative and try to make their online store a little more user friendly and functional. there’s got to be a way to keep older games and still not have to scroll through a huge list of stuff to find what you want.
