Well, there are efforts to have an Italian cluster (http://www.h-farmventures.com/en/ and similar), the European cluster is probably London, and the global cluster is SV for sure. It's not _that_ terrible.
Sadly, h-farm does not really play in the same league of even third rate incubators in sv, both from cash and expertise perspective... And it doesn't look like it's going to change anytime soon
