So should they not have posted at all or should they have used a different title?

If your article on how to architect for uptime ends with how the authors system isn't architected for uptime I don't think they should have written it. How do we know their advice applies once they actually institute the changes they talk about?

This is a really good point and I appreciate your viewpoint, but just because I wrote the article for/about stack exchange it doesn't preclude me from having done it differently at a prior employer.

Talk about that then? It make it clear you're not just talking out your tush some way?
