My suspicion is that it's not that 2.0 never caught on, but that once 2.1
came out, there was no reason *not* to use it.... except for those
circumstances that had people stuck with 1.5.2. Similarly, I think that
once 2.2 has been out for a bit longer (and more binary packages are built
for it--notably, I'm still waiting for ActivePython to have a 2.2final
release...), there won't be much reason to hang on to 2.1 (presuming, of
course, that RH8.0 uses 2.2 and not 2.1). At least, that's what I'm
*hoping* will happen. :)
