Hi Stevan,

I thought I sent it to the group, but perhaps not.

In any event your note said much of what I said. I do not understand 
how my saying complementary not competitive can be construed as 
supporting the disruptive technology thesis.

I should make clear that my comparison was of use during July 2005 of
articles published during 2004 in the Astrophysical Journal.  These
articles were published in 2003 and 2004 in astro_ph.  The main use of
astro_ph, like almost every publication, is for newly published
articles.  astro_ph is very heavily used in this manner, indeed it is
likely that the readership of any particular article is greater in the
~6 months it is only available as a preprint in the arXiv than it is in
the first couple of years it is available from the journal.

Because the main use of astro_ph is before the article is available from
the Astrophysical Journal, and after it is published the use is mainly
from the ApJ (for the same article) the two services are more
complementary than in competition.
