I don't know whether I am in the Linked Data scene ;-), but I am
convinced that bNodes can be useful. For example, if I have a lot of
value nodes that hold together quantities and units of measurement. In
such cases is pretty much unnecessary to ever reference to that node
individually from outside the model in which they are defined, so using
bNodes seems to be perfectly okay. Plus, you avoid the risk of URI
collision by accidently reusing an existing URI.
For me, bNodes can be in the RDF world what local variables are in
programming.
