We're running Microsoft Office 365 as a our e-mail (Outlook/Exchange), instant messaging (Skype for Buisness) and cloud storage (SharePoint Online). I'm doing a heck of a lot of research and note taking, and that's being captured in OneNote (desktop version, so I can take advantage of handwriting recognition on my Windows tablet).
I've worked in IT for 20 years and in my spare time have developed a number of websites, but I've been pleasantly surprised at how easy it's been to pull together all the platforms and bend them to our will. If anything, getting the systems up and running has been the easiest part of it - leaving more time for the hard yards of research and content production.,
Of course I've learnt a few tricks along the years, but there's really nothing stopping a non-IT person getting a pretty big online presence in place for their business for a couple of hundred dollars and a couple of days effort.
