It seems he did both: before double-checking with the community, he
cited one of the leading metrics commonly used for identifying OS
market share, the aggregate stats at NetMarketShare:
<http://www.netmarketshare.com/report.aspx?qprid=11&qpaf=&qpcustom=Mac+OS+X+10.5&qpcustomb=0>
It's difficult to find stats that break down OS X usage by version,
but if you can turn up any recent ones from Chikita or others it would
be helpful (the most recent I could find from Chikita were more than a
year and half old).
Looking around at the rest of the Mac developer community for guidance
shows that Firefox dropped support for 10.5 last year and Chrome
dropped it in 2012.
Most of Adobe's products currently require 10.6.8, including Flash
Player which is extremely dangerous to use without being able to keep
up with critical security updates.
Apple's last version of Leopard was 10.5.8, released in August 2009.
AFAIK they've released no security updates since then, compounding the
dangers present by running outdated versions of Flash with a wide
range of known security exposures Apple has since fixed in supported
versions of OS X.
If you know of anyone who absolutely must run OS X 10.5, please remind
them that it's safe only for local work unconnected to the Internet.
Schools needing access to web resources like Wikipedia using systems
that are unsafe on the Internet can consider inexpensive options like
the Internet In A Box project to bring critical resources into the
classroom without external network connections:

And of course the useful life span of older computers can be greatly
extended by installing Linux on them.
For example, Xubuntu (the lightweight Ubuntu variant) runs well on
most older computers, and v12.10 will continue to get security updates
through October 2015. Version 14.04 will be released in April, and
will receive security updates through April 2019. A PowerPC build of
Xubuntu is maintained by the Ubuntu community as well for those who
need it.
At which point it might be not a bad idea to point out that RunRev's
time might be better spent putting a Linux PPC version of Livecode
together rather than anything for Mac OS 10.5 or lower.
Richmond.
LiveCode runs well on all Ubuntu-based distros v12.10 and later, and
on many earlier versions as well but since those are no longer
receiving security updates I can't recommend anything earlier than 12.10.
