To put this in content. Right now these activities account for 63.3% or online usage, 85% of which can be provided by SharePoint.
This makes SharePoint a pretty obvious tool for web publishers but also for companies hoping to exploit skills users develop on the web to work. And the workforce is learning these skills now at a ever expanding rate, whereas use of traditional system, spreadsheets, or other methods of content creation and communication are not being learned to such an extent.
It simply makes sense to go SharePoint.
