I agree with Merlin, There is a surprising big number of "good"
technology companies (including Google) out there using MySQL. For
sometime I have been wondering why and have come up with a few
(possibly wrong) theories. Such as: these companies are started by
application developers not database experts, the cost (effort) of
changing to other database engine is substantial given that that
probably there is already so much inconsistencies in their current
data setup coupled with considerable amount of inconsistency cover-up
code at the application programs, and maybe the IT team is doubling up
as a fire fighting department constantly putting out the data driven
fires. This is then compounded by the rapid increase in data.
