The big issue according to Balkan is the incentive to join an instance that seemingly absolves users of such problems, this however just kicks the can down the road. For Balkan, instances should be limited from getting too big and ideally we should all have our own instance linked to our own domain, the ultimate form of verification.
I have tinkered with using my site as an ‘instance of one‘. Although I liked the idea, I could not get it all to work how I would prefer, so I persisted with my POSSE approach. This also have me thinking about Jim Groom’s reflection on life in the cloud. I guess the reality is that there is always a cost.
