And a few more...

Among the top 20 browser types we see at www.wishing.com (omitting
comments and platform types), 16 of those are "Mozilla versions"
(presumably including some diffferent IE versions in those counts
as well).  Mozilla versions 0.9 and 1.0, for instance still appear
in the top 20.  [That's out of 284 different browser makes/versions
(of which 62 are Mozillas).  For the complete list and percentages,
see www.wishing.com/webaudit/browsers_details.html]

There's real problems involved trying to do content negotiation
simply among the different Mozilla versions (many of those top 20
Mozilla versions don't do Tables, or if they do, those versions
have notable bugs...).  AND there are within-version platform
variations (i.e., while all 2.06a might do JavaScript, only some--on
certain platforms--do Java yet).

User-Agent-based content negotiation is very problematics under
these conditions.

p.s. Other sources of current User Agent breakdowns show similar
numbers.  See also:
