Good points, Ed.

It makes sense that vendors would go with the path of least effort, especially when it seems to their advantage to measure in that way. Thus, the much more difficult task of proving real marketshare falls to this project! With IBM on our side, as well as Sun, we might be able to figure this out, or at least promote our interpretation a little more.

Firefox also benefits in that websites keep stats of which browsers are visiting them. In a slightly similar way, we can search for the number of ODF vs. MSOOXML documents available on the web (and some have done that and written about it), though this is still an inaccurate proxy measurement.

At the very least, we can strongly promote our meme, which may cause users to demand a reinterpretation of the landscape. Breaking down the 95% assumption will benefit us in many ways.

Benjamin,
good observation. What are the other marketing departments of OSS saying about this? Mozilla, Apache, Ubuntu, ...? I think this is a wise spread
issue if true and we should focus on making all in the OSS community
aware of it. Can we try to collaborate with some economics professors, in order to study the general phenomena and then use their research in order to blog, give presentations at conferences, unconferences, post in
mailing lists, etc.

Having worked with a lot of market research firms in the past (an
industry filled with conflicts of interest and poor methodologies),
there's a very simple reason why they like to use revenue numbers: it's
much easier to compile.  They simply call up a company and say, 'we're
doing a market share study and would like to know your revenue numbers
for x product.' Then, they tally up the numbers and issue a report. In
other words, there's very little primary research involved.  A REAL
market share study would have to look at actual usage but that means
those doing research would have to do some real work and solve real
problems.

The revenue == market share phenomenon exists in many markets,
especially software. For example, mysql hardly registers in some market share studies of database servers because a significant number of users
get it for free.  It also doesn't help that those sponsoring these
reports are often the big commercial vendors themselves, i.e. Oracle,
IBM, Microsoft, etc.

The only reason why Firefox doesn't suffer from this problem is that the
alternative is free too, e.g. IE.

I think we should pose the question to the researchers, how they measure
the market share.
