When I read this tonight, my jaw dropped and my anxiety and stress level went up a few notches. The answer is no - I run a few multi sites and work on another set of multi sites which I just did a training on for my client. How would you manage users across 100 single site instances, each with their own permissions? And, to click and deploy plugin or theme updates individually? Sure, if you had some system of checks and balances to report which sites broke. There are so many reasons to keep multisite operable for the non-development crowd. Let’s please keep multisite because the cost of taking it away and forcing everyone who uses it to restructure their workflow is enormous. How would one go about setting up and migrating 100 sub sites into single site instances and then you have to add one user to 100 sites with the same user pass and send them a list of URLs to login to! Imagine the support email from a user who forgets which site in the network they can’t login to? I don’t know…I’ve been using multisite for YEARS! If it were taken away it would be costly. I know some people even sell hosting plans off of multisite, so that would cause them a lot of pain to have to export every site and import into single site instances at their host. My WP Engine plan is $290 a month for 30 sites. What if I have 100? What do I do then? What host can I go with the same level of service who will give me 100 install? WP Engine allows multisite with one click in the CPanel. All the WP Engine customers would be SOL if multisite went away, because then they’d be in the hook for a lot of money. I don’t know if he mentions that in his proposal, but that has ti be factored, as well.

Forgive any typos. On my iPhone…hoping my blood pressure goes back down.
