Don't tell me, show me, showmedo
I recently opined the general dearth in the use of the Web as a vehicle for explaining/detailing complex phenomena that involve movement, 3-D views and so on. Stuff that no amount of colour plates or line art in paper-illustrations can ever match.
Interactive software of the GUI persuasion is a good example of this. No amount of screen shots can come close to actually looking over someones shoulder and watching them do something.
So, I applaud initiatives like showmedo and wish them every success. I'm sure the Python training videos will be a big hit.

AJAX - nearly 2007 already
One of my pet theories is that no idea in computing every really takes off until at least ten years after it has been first hatched. XML goes back to the Eighties. So too does Python.
Would you trace AJAX back ten years yet? Its getting there believe it or not.
Back in 1997 Jon Bosak wrote about the slogan "XML gives Java something to do". http://www.ibiblio.org/pub/sun-info/standards/xml/why/xmlapps.htm.
He was talking about client/server computing, browsers etc.

Ultimately, all semantic identifiers are incorrect
Stuart Weibel talks about that old nugget, the globally unique persistent identifier.
In Kripke-speak, this is a rigid designator.
It is very appealing to embue rigid designators with semantics. Sometimes by making them proper nouns. Sometimes by making them intensional.
The hard problem is finding any semantic that is rigid through time and in all possible contexts. Hence the magnetic pull towards opaque identifiers such as numbers.
The Web is a wonderful example of what happens when you let everyone loose to create their own identification schemes. Identifiers are social constructs. The problem of identification is ultimately a problem of language.
Human language is surface chaos with a consistent underlying form. As byproducts of language, we should not be surprised that identifer systems are similarly chaotic on the surface.
Utterances are always a rich steamy broth of the extensional and the contextual. The context bit is what makes us human. We take short-cuts in utterances all the time. That is the context.
Obviously, this drives computers mad because computers don't do context.
It also drives non-computing folk mad because they cannot see why the heck the computer cannot just use the context like everyone else.
Computing is a fun field :-)
