This page offers pointers to some essential and interesting services that business owners, product managers and producers of digital goods should know about; some old some new (this list will grow and grow). You might think of each technology as a skill to acquire and to gain experience in too.
For example: Conversational software for persistent collaboration covers a few different application categories. The area is fast evolving with lots of feature/functionality replication washing across all the various offerings...
Team communication tools: any kind of open Wiki, Slack, Google+Hangouts, Skype, etc.
Social networking tools: FB, SnapChat, WhatsApp, Yammer, LinkedIn, etc.
Collaborative software: any kind of Wiki, plus a whole range of other products mixing database, web and markup (like wiki, structured text, restructured text, rich text, native Word, html, etc), with features like fine grained (or not) user/account/rights, workflow, content management, discussion, blogging, file systems, change tracking, versioning, tagging, bookmarking, etc.
Basic digital competencies: graphic design - the use of colour, space, perception for display, communicating, representing, aesthetics; UX, ID, UCD; the presentation structure of web pages; image editing and manipulation; information management.
