Wayne, I do the same thing.  I think of it as the equivalent of citing 
"t.p." or "p. [whatever]" in 670 when the source is a book.  There is an 
example in the NACO Participants' Manual. (Section I: New Authority 
Records/ 670 Field / XV.Citing Internet Resources, third example:  |b 
contact us page -- an especially nice example for the informal 
internet-flavored language, which is indeed what we usually end up citing.)
