I don't really have a formed opinion on this topic. My main
attraction to whitespace as a delimiter is that it keeps the URLs
clean (avoiding /t:best%20of%20breed)
Well, take a look at the guy's special web page devoted to documenting
his great linguistic contribution:
http://vanderwal.net/folksonomy.html
He devotes a lot of text to the circumstances of his coinage, while
misspelling Joshua's name. I find this symptomatic of the general
process. One set of people does interesting things without a lot of
fanfare, and another builds an elaborate intellectual superstructure
on top without adding value. It's a kind of minor intellectual
parasitism whose main victim appears to be the English language.
Well it wasn't really my "argument", I was just sending it to the list
for discussion.
If he is someone who has worked on a lot of projects in the space,
then yes, this does strengthen the value of his recommendations....
