To save time, I'll just refer to Richard's post re. Blank Nodes [1].

We do want a WWW based Global Data Space that has a high amnesia 
quotient. Remember, your G+ response to my post [1] about TimBL and Ted 
Nelson being separated by a common desire (expressed in their visions) 
for a Global Linked Data space driven by Hyperlinks? You couldn't find a 
Reference to one of your old comment about the artificial dichotomy of 
their visions etc..

The WWW has a shortening effect on "attention" while upping the ante on 
"memory" and "recall". Therein lies the conundrum :-)
