Feedback: data processing documentation on rock-robotics.org

I recently wrote some documentation about a few "patterns" in data
processing (patterns that has some specialized support in Rock). A lot
of the text deals with explaining the principles, which is orocos- and
rock- unspecific, so I thought I would query some feedback from the
community

The documentation is here:

Comments are very welcome !
