Fabio,
I would hope that there is a difference between blogging on a Wordpress site and on SCN. People who comment on blogs here are SCN members, and if they are abusive, they can be guestified, so I think for the most part they are not. All of us who blog here are putting our opinions out there for anyone who wishes to agree or disagree, and that is part of the deal of the community. There are plenty of outlets for SAP infomercials.
Cheers,
Gretchen
