Guy Kawasaki has posted a follow up to his post 'A review of my first year of blogging' which sparked a flurry of interest from bloggers because it revealed just how little Guy actually makes from advertising on his blog (and by implication, how little money there is in online advertising)

The new post - entitled 'The Short Tale: Much Ado about Not Much' goes further - explaining that he did not mean to cause any controversy and explained, if not for money, why exactly Guy blogs.

He says:

In case you’re interested, the reasons that I blog are:
To increase the likelihood that “two guys/gals in garage” with “the next Google” will come to Garage for funding.
To help companies and people that I (a) like, (b) have sometimes invested in, (c) am sometimes advising publicize their products and services. This is also known as “alignment of interest” as opposed to “conflict of interest.”
To be able to tell Web 2.0 entrepreneurs how full of shiitake they are if they think that advertising is a slam-dunk business model. Essentially, a Web 2.0 company would have to be 10,000 times better at selling advertising than me before it gets interesting.
To test ideas with “reality checks.” How many guys have 30,000-person focus groups?
To tap the “wisdom of the crowd.” For example, ideas for my next book. How many guys have 30,000 people providing new-product ideas?
To make meaning and fulfill my mantra of “empowering people.”

As I explained - I personally never imagined that individual bloggers would blog for the advertising revenue. Not successfully anyway.

In case you're interested - here's the reasons I personally blog here on the Touchstone blog.

To join the daily discussion about topics and issues I am passionate about.
To explain to our testers/users, partners, investors and anyone else who will listen why we should all be paying attention to Attention.
To keep everyone up-to-date about our challenges, goals and intentions with Touchstone (as guy says, how else can you get such a large focus group).
It helps me structure my thoughts and clearly express them for our team and the wider community to see.
To encourage people to connect with me if they have similar ideas or potential opportunities that could benefit us both.
To be heard...
