I've come across the following characterizations of Ne dominant types:
  • Bouncy, life of the party, boundless enthusiasm, good talkers, bla bla. Can't remember the exact words, but you'll know what I mean.

    ENFp = shyest of all the extraverted types. ENTp = pretty shy as well.

It looks like a contradiction. It probably isn't one. How does this correlate? If Ne-dominant extraversion doesn't mean that we're outgoing and bouncy all the time, then what does it mean?
