I am a picky reader. I prefer to take topics one at a time and study them very closely. Recently I decided to start going through all of Warren Buffet’s Letters to Berkshire Shareholders.

The past few years Warren Buffet has made reference to his partner’s book (Charlie Munger), Poor Charlie’s Almanack: The Wit and Wisdom of Charlie Munger. The book went on my “to read” list. However, after seeing an excellent post on Marc Andreessen’s blog — The Psychology of Entrepreneurial Misjudgment, part 1: Biases 1-6, I immediately ordered two copies of the book.

Charlie Munger preaches the use of multiple mental models when approaching business and investing. I thought that I had a similar approach. That is, until I read Charlie has about 100 (I’ve been using maybe 4 or 5.)

The book gives a run down of Charlie’s life along with a collection of 10 talks he has given. There is a fair bit of repetition in the book’s 500 or so pages, but not so much in a bad way. Other than that, I have nothing bad to say. Do not expect a point-by-point list of what you should exactly do. This is a book about how to think so you can solve problems.

A blog review can’t do this justice. If you want a preview, check out Marc Andreessen’s post I linked to. Like it, you’ll like the book. You can grab a used copy off of Amazon, or get a new copy direct from the publisher.

In my previous post I said that Google is a data company, Yahoo is a content company. How so? They are both search engines, right?

Both Google and Yahoo provide lots of web services. Yahoo always was a portal & search engine, but over the years Google has continued to add more “portal” services — Google Maps, gmail, Google finance, and so on.

Take a closer look at the companies. Compare Google Finance to Yahoo Finance. One of these companies needs an engineer with a cup of coffee, the other needs an engineer, editor, and staff.

Yahoo is focusing on their own on-site content because of the display advertising revenue, there is no doubt about it. There is a problem with this approach. Short term, its not helping them keep up to pace. Long term, this model risks killing their company.

Yahoo is demonstrating a strong interest and desire to pursue an old model — a centralized content distribution structure (walled garden has been a popular phrase lately.)

Consider the two models. Yahoo pushes traffic to their own properties, presumably of good quality content. Google pushes traffic to outside properties, of the most popular content. Google doesn’t have to struggle or focusing on providing fresh content of the best caliber day after day. And, to make things even better, every hit to something the audience like is yet another point for Google’s brand value.

Take a look at YouTube and compare their traffic data to the monster video sites that existed years prior (such as eBaumsworld.) The owners of eBaumsworld certainly weren’t generating their own content. Like Yahoo, they were re-ordering and collecting outside content, presumably by hand. No matter how good the human element got at it, at some point, Youtube’s exponential growth rapidly dwarfed these older video sites within mere months.

Why? Because automated systems can sort and aggregate data far faster and far better than human editors.

Weigh these two things: As Google’s engineers work on rolling out next generation systems Yahoo’s editors have been building sub-portals aimed at a specific age demographic of women.

10 to 15 years out, where will Google be? Where will Yahoo be?

I’ve spent a lot of time weighing content verse data myself. Data won, I changed my business model. More on this topic in the near future.

Tech bloggers everywhere have been talking and throwing out predictions over the failed Yahoo Microsoft merger.

I’ll keep it simple. Google is a data company. Yahoo is a content company. That difference is night and day when it comes to focus and performance.

Content is a fine business model. Long term, a “be everything” model it is destined for failure. Niche publishers and aggregated feeds will grind away at their audience and profit margins.

Short term, the mis-focus has caused Yahoo to fail miserably by screwing up Panama. Also, for far to long they allowed garbage traffic access to the same PPC feed as high quality publishers and domainers. And thats just the beginning of the list. These are mistakes data companies don’t make. Google sure didn’t.
