Sorry if i mis-understood, but
What I read from this is every company needs a "Cloud evangelist" to drive cloud adoption forward.
No, what every company needs is a bullshit filter. Cloud is actually a pertinent name, in really its just mist and vapour. Cloud does not reinvent IT, its just a rebadged f*cking hosting company or online service.
BTW i have no issue with online services, i make usage of them both personally and professionally. But I do think people who still try to evangelise it should be sent for BOFH style therapy.
