Measuring the adoption of Linux on the desktop is a difficult proposition and has caused controversy as to how many users there actually are.
As Linux systems are typically downloaded, copied and distributed for free, the usual methods of tracking sales numbers do not apply in gauging numbers of Linux desktop users. This use of website counters to identify operating systems also does not produce reliable numbers, due to such factors as:
- individual websites do not attract a representative sample, due to their content.
- spoofing of addresses.
- problems tagging identification strings as to Linux or even distribution results in high numbers of "unknown operating system".
- identifying computers that operate from behind proxies.
- the multiplying effects of botnets which tend to create the illusion of more insecure PCs, running Windows systems.
- the fact that not all PCs are connected to the internet and used for web browsing.
- one download could result in none or whole site installations

Famous quotes containing the words adoption and/or measuring:
“Frankly, I adore your catchy slogan, Adoption, not Abortion, although no one has been able to figure out, even with expert counseling, how to use adoption as a method of birth control, or at what time of the month it is most effective.”
—Barbara Ehrenreich (b. 1941)
“As an example of just how useless these philosophers are for any practice in life there is Socrates himself, the one and only wise man, according to the Delphic Oracle. Whenever he tried to do anything in public he had to break off amid general laughter. While he was philosophizing about clouds and ideas, measuring a fleas foot and marveling at a midges humming, he learned nothing about the affairs of ordinary life.”
—Desiderius Erasmus (c. 14661536)
