It's been great at
http://geekli.st and we run a full node stack. It is true error handling is an issue sometimes, but that's over shadowed by the quality of engineers looking to hack in node. Most common reason I hear for someone leaving a company... "I wanted the opportunity to hack in node at work" - not once, twice but dozens of times. In an age where finding top notch teams to build your stack is really hard, what code base you use is really important to attracting top talent.
