Woven is certainly very usable in it's current state -- if you want to
do simple-to-moderate things quickly, it can be very useful. However,
it's complexity made it difficult to do some of the more ambitious
things we are trying to do, such as semi-transparent form handling, and
serverToClient events. But there are a few people who have built (and
deployed) fairly complex woven applications. The fact that nevow exists
doesn't detract from that.
nevow was originally a research project -- a weekend's worth of hacking
whose benefits turned out to be so great that we decided to focus on
bringing it up to a usable state for Quotient as soon as possible. And
that's where it is now.
Most of the woven concepts -- template and code abstraction using a
DOM, reusable partial page renderers (Widgets in old woven, renderer
callables in nevow), all of the concepts needed to know to use
twisted.web -- carry over to nevow. The only thing that's really
changed in nevow is a few names, and the code is VASTLY simplified,
well tested, and thus far easier to understand, design semantics for,

nevow will be moved into twisted after a period of
stabilization/development in Quotient. Since twisted is a large project
with many external developers using it, and quotient is a smaller
project that is mostly a small core team of development, we felt it
made sense to keep it out of twisted proper until the development had
stabilized. Since nevow has the benefit of being a complete rewrite of
all the *best* parts of woven, and none of the bad, stabilization has
been remarkably quick. So expect to see nevow in twisted fairly soon.
In the meantime, woven will continue to be maintained with bugfixes,
and nevow is fully usable outside of quotient -- even to the point of
being fully usable without twisted.web (as a cgi, or in zope or
webware, for example). I should also mention that there will probably
be a compatibility layer for nevow to render old-style Woven classes
sometime in the future. It is amazingly simple to add rendering
functionality to it since it uses components to render the dom (which
is really just a list of any python objects)
If you are doing any new development, I highly encourage you to take a
look at nevow, if for no other reason than you can have a hand in
shaping it's development. I would very much appreciate feedback about
it, especially now, since the code is very, very short and readable.
