I think ENFPs are much more direct. They do seem to have their own version of cocooning, although I don't know enough about it yet to truly comment. I know though that despite their great amount of social activity, they can be extremely private in other ways.
I've also found it interesting to see the big differences in how ENFPs varied from INFPs in following a conversation (ENFPs are way more scattery and flit from thing to thing, whereas the INFPs are more focused and likely to reprint the questions and answer them point by point.) I think it's that Ne thing we were talking about before.
The ENFP description was more comprehensive than the INFP one. However, both kinds would be less likely to present a humongous summary of themselves for people to comment on. They'd be more likely to go with subjects as they came up.
In both cases, people would be reluctant to speak to anyone else's experience. Also, no one exactly has stepped forward as the "host" of either thread, even though Seymour has remained quite involved throughout.
Despite jumping around quite a bit, I also notice that the ENFPs crave more order than the INFPs in presentation. If it's not there, their attention is likely to move elsewhere.
