This is actually a permalink. There is some noise after the ? that you
can ignore. If people bookmark the link or send it around, that's no
problem.

> I could make a permalink like this:

This is the same permalink as above.

a) As far as i know, this modification doesn't change anything about
the link, it is just a different encoding. The resulting URL is the
same.
b) As long as you only remove the _s, _k, _n and [0-9]+ keys that
doesn't change anything, you will only loose the session information.
The blog component actually does something like that to display a
nicer link.

Doing absolutely clean URLs is possible, however it requires some
heavy Seaside hackery to avoid loosing functionality. Unfortunately my
time working on Pier is very limited at the moment.

I only realize now that you are on VisualWorks. Looks like a bug in
the request parsing and URL decoding there. It works without problems
in Squeak, no matter if I use + or %20 in my URLs.

Yes, it is.
