What's the point, then? Google will (or should) spend just about as much effort keeping it live for enterprise users as it would for the rest of us.

I don't use it often, but occasionally find useful communities there, especially concerning technical subjects. Now all of that is going to disappear.

It's annoying that Google apparently prizes the opinion of enterprise customers enough to half-abort the plan to shut down Google+, while for some reason maintaining a stubborn insistence on removing its access for the rest of us. Yes, this will be another point to add on the list of reasons to never become invested in a new Google product.
