I did not do anything to discredit anyone and I take exception to that term.

I published an example of WHY CentOS does not release anything until we
check it via QA.  Once something is released, it can not "come back".

What I said was what CentOS does if we have a problem (look at other
distros to see if they have the same problem).

I did not say that SL does not care about compatibility, nor did I make
any claims that CentOS was more or less compatible than SL.  If users
what to find out the answer to that, then they can take the time to run
the tests.

SL is a great product.  If I did not use CentOS, I would use it.

However, CentOS is locked in a battle with Debian as the "Leader of
Webservers" on the top 1 million websites for the world. 29% of the
Linux websites in the world use CentOS:

CentOS has been the "Market Leader" for web server installs on the top 1
million websites for the last year.

You can like it CentOS or dislike it, however the numbers do not lie.

We will, therefore, release our products after we QA test them as we
have to maintain the quality that people have come to expect.

And I have known that all of YOUR concern about the process has always
been so you can try to steal our users Dag.  If you want to steal our
users for your rebuild then you can do that.
