Gulenko's description says about them that they are 'quiet, even though they are extrovert'.
Smilingeyes' work identifies their accepting function as 'socially closed', which means they are only secondarily 'involved' in social matters.
They are 'the most abstract of types' according to some of Smilex' estimations. Both of their functions are 'internal', which should mean they don't like to take rigid stances to issues but rather take an accomodative position. In addition, they are bona-fide perceivers and extroverts, which we might assume points to a need to look outward for motivation.
In one thread I estimated the 'social confidence' of functions and types, which resulted with ENFp as one of the types with the lowest values. (though this did not take temperament based extroversion in account)
So what kind of a picture of a person do these attributes create? Is the ENFp the type most likely to mistake themselves for introverts or something?
