This is a great how to article on remote management. The tools he lists are all there. The author mentions Skype, Slack, G+ Hangouts, and then surprisingly WordPress. Would the author care to discuss how he specifically has used WordPress to remote manage a team? I think the issue is that most managers don't want to remote manage which makes me wonder, "Why?"
I worked for Mullenweg for a year at WordPress.com to write a book about all of these questions. It documents all the tools I used and what life was like as a remote manager of a development team.
Do you recommend this book to understand remote working dynamics at Wordpress ? Learning from companies that succeeded in setting up the remote working practice is definitely the best way to understand if you can put the process in a bottle.
Anyway thanks for sharing this title.
The direct answer is most managers have no experience managing remote workers. Certainly that's not the entire story but it's a new way of working and many organizations reject it for its novelty without understanding it's advantages or what investments have to be made to get them.
