Italian citizen here. The experiment was interesting, but it's implementation is quite sub-optimal: when you have to govern, you recognize that matters are quite more complicated and you need to compromise. This is not necessarily wrong, if you have the intellectual honesty to admit that the utopian purity that you assumed as the main differentiator between you and the "old, dirty politics" is, well, an utopic oversimplification.

in theory, yes, in practice, not much.

Online voting was used a few times (election candidates, electoral law, presidential candidate), but for some cases the options were pre-decided (i.e. which party should be chosen as an ally in the european parliament, only 3 options) and in some cases decisions were dropped from "above" (i.e. the current party "Directorate").

And mostly, it has not been used at all.

One now-deceased party founder had a strong vision of internet-based democracy, but it hasn't really materialized _yet_ .
