I am the technical leader of the intranet at Prodesp (www.prodesp.sp.gov.br). We are studying the adoption of sharepoint for our new Intranet Portal. The sharepoint has evolved, and that's a good thing, but Microsoft needs to pay more attention to tenants with multiple companies, otherwise, if it starts to restrict features, forcing you to acquire a tenant for each company, this will be an impediment to our adoption.
