This book is volume 1 of a set containing conversations the author has had with hundreds of people on LinkedIn on the subject of Enterprise Architecture. Subsequent volumes continue the discussion from where it left of in the previous version.
There are no dates as such, but the set generally covers 2010 to 2014 at which point I stopped because I had been put on moderation or banned from most of the groups where discussions were going on that it was pointless to continue. They had won.
I have published it not necessarily so people can see the content (although that is useful in itself) but more because I think it’s useful for people to witness how these debates "work". Perhaps it would be useful as a Psychology analysis regarding how online conversations are conducted. Also, parts of it are quite funny ;-)
