Yes. I agree. Let me add some comment along Quentin's (abbreviated)

A year ago, I (S.M.) wrote to the SIGMETRICS list:

NO: there was no reaction whatsoever. MAYBE the topic I suggested is

Although Quentin is to me on this, too, mostly correct, I'm adding
for good measure that the List did in fact bring out even an abstract
of a paper of ours on evaluating domestic journals. Perhaps because
the journal we published it in (this year - 2000) is covered by

Notwithstanding the brave attempts of offering theory of citation, we
enlarged the "collection of empirical studies" with the hope of at
least presenting some food for thought (the time span was 10 years of
publishng + 20 years of citations to the source papers):

context versus the frequency counts of citation histories. Journal of
the American Society for Information Science, 49/6, 507-516.

Well, this indeed is an ongoing (but not in this list!) discussion.
Bearing in mind all the caveats for using citation analysis in
decision making process", again for good measure - here is my
experience at the periphery where the ugly side of indiscriminate use
of citations does come in the foreground:
