The domain name was a compromise given what remained available according to ICANN.
Nueron.com or Nuero.com would have been somewhat ideal had they been available, meuron.com (micro-neuron) has been taken by a Japanese already, Euron.com was at some stage selected, but it turned out to have been occupied too. Iuron.com was a short and elegant name that did not contain the geographically limiting 'euro' either. The preceding I refers to 'Internet' which is the main target domain.
The reasoning behind the name is associated with aspiration to form proper knowledge with a networked hierarchy. Time will tell if the complex task can ever actualise without ad-had workarounds and simplifications.
