Ah, yes - this is probably the crux of it all. Hmmm. Perhaps we can make these
"chapter" Projects more robust against change simply by getting a better grip on
our dependencies (which we are slowly going to do in SM1.1 and Squeak 3.5).

And it will be hard to write tests for these Projects - you know, the classical
problem of test exercising a UI.

But sometime we just have to start biting the problem of maintaining object
structures in the face of change instead of rebuilding them all the time. :-) Right?

Perhaps we are getting closer to that point in time.

Yes, I think we have a few advantages today:

1. The community is larger. More people can help.
2. Large parts of Squeak have slowed down and are pretty robust.
3. We have SqueakMap and StarBrowser to base it on.
4. The community is slowly moving into a mode where people can "claim ownership"
and take personal responsibility of parts of Squeak. This is IMHO a *very*
important social mechanism that we haven't really had before. (if anyone wants
to know more what I mean by this, just ask)
