often some steps beyond the technologie. In general it's much better

Different widget/schema technologies for add/edit forms and standalone
forms, escpecially atapi.Schema vs. zope.schema.
Archetypes make it hard to separate between interfaces and
implementation. Classes based on Archetypes are always complex and don't
fit in a world of "orchestrating small pieces of software". Complex base
and mix-in classes make debugging/profiling hard.
Performance, especially related to indexing. (ZEO helps scaling towards
large amounts of page impressions/vistors. Improve handling of huge
amounts of content objects.)

* Documentation/Tutorials should not only say what they are doing, but
also why they are doing it this way. (Many do.) Documentation marked as
outdatet should tell what aspects are outdated. (Often this is related
to small pieces only, e.g. defining s.th. in now done using GS.)
* Keep the official roadmap up to date and let the people use this to
decide which technologies are future proof and which are not.
* Try include performance related improvements into the core
(QueueCatalog, collective.indexing) as every site out there should
benefit from performance.
* Keep in mind, reusing technologies where sensibly possible,
is developer friendly, e.g. zope.schema + z3c.form might be used on
ZODB, RDBMS content and standalone forms. The persistence layers for
RDBMS and ZODB should be too different.
