Why Webbrowser statistics lie and just don't say anything

There are many more factors to consider, e.g. Squid, "Unknown" due to
diversity (usually thrown out of stats, but accounts for ~10%), user-agent
forging (for MSIE-only sites)...
Many more reasons for error were discussed before. They work in Microsoft's
favour and grossly underestimate the prevalence of GNU/Linux.
