It seems to me the Unicode web site has gone thru a number of changes
recently to provide information more clearly and directly. That was
a good start.

It perhaps would be good if those of you that understand Unicode
well, and participate in developer conferences (Java, XML, etc.)
would propose and deliver talks on using Unicode in those environments,
and help spread the word.

Perhaps creating a conformance test suite would help people understand
the requirements...

Or minimally a checklist that developers can use to self-evaluate their
Unicode compliance would help.

Maybe a checklist for authors would be good too. A list of misstatements
to avoid...

Other ideas?
