Posted by Jamie Orchard-Hays <ja...@dang.com>.

Vijay,

Yes. Our Tapestry 2.3/Cayenne projects have been running in production for
close to a year. At peak traffic times we serve 5-7 million page views a
day.
We're very happy with tapestry thus far.

Re: Tapestry stability
Posted by Harish Krishnaswamy <hk...@comcast.net>.
I am not quite sure what you mean by stable here. If you mean product stability in terms of a
release then I would say Tapestry is pretty stable, I have been using it in various production apps
with no problems. If you mean market stability, I think Tapestry is gaining market strength with
more and more users/applications starting to use it.
