Kinda a long response but I'm being *thoughtful* lol
I think satine made a good point in the other thread that Fe users are more about continuity while Fi users abundance of supply comes in spurts. Too much contact and Fi users are depleted.
This is interesting...my Fi well never goes dry. But I get what you mean about 'continuity'.
For love/affection I need constant activity to keep it full and brimming, it doesn't get depleted. I have almost endless affection and good cheer for those I like, especially my 'favorite people' (which includes pets...LOL). The only area my Fi can get really burn out quickly is when I'm taking on others pain/drama or am around a lot of chaos/ugliness/darkness. It's like bad vibes suck the energy out my psyche. Fi is receptive whereas Fe is directive so Fe users definitely have the advantage here as they are immune (compared to Fi users) to intangible 'bad vibes' and and can be continuous in their efforts/activity in certain arenas. For Fi users, we have to remove ourselves to restore the bubbly. When an Fe burns out it's because of the effort, when an Fi burns out it's more because of the fatigue of experience.
As far as socially, it's really hard to burn me out socially.
I need to have continuous and varied social interaction or I start drying up like a dirty sponge in the sun. My neurons start rusting and I fold in on myself like a dry monk. It's really bad!
The kicker is, the social stimulation needs to be consistent *overall* but it doesn't necessarily have to be with the same people. But, I do have a core circle of friends that I seek to hang out with consistently because I *want* to and I will miss their presence. I think it's common for Fi heavy folks to have consistent friendships because they are fueled by Fi need and impulse. Fi is "I do what I want to do/what I feel like doing". And for my 'favorite people' they are my favorite people because I prize their company so much that I continually seek them out. If I did not have that unquestioned, gut impulse I do not have the mindfulness or enough of that kind of social sense/skill to maintain relationships 'just because'. It's just a more extreme, slightly warped version of what makes any consistent friendship work. Also, I'm sure ENFPs can seem opportunistic in the way they start and develop relationships. Again, I think that's an ENXP thing, since it's mostly a matter of Ne leading with no J to direct.
I have become more aware of 'touch and go' tendencies and seeming inconsistent behavior by observing OTHER ENFPs though.

I've also gotten used to the 'touch and go' and inconsistency with INFPs who have even more Fi (poor INFPS...lol, I kid)
When an another XNFP does something inconsistent, sometimes I don't know why, but I chalk it up to being ENFP and 'Fi'. Fi is so individualistic and personal and often secret or hidden (sometimes reasons/motivations are unknown to the person themselves because the are so deep in it they have no objectivity).
I notice a tendency for some ENFPs to speak first without giving much thought of what they're saying; which can often have the effect of creating a huge mess if it's misunderstood by the other person or hits a nerve. For me, when I say something, I've already given some thought as to what I'm saying.
God bless you INFJs for being thoughtful.

Someone has to do it! LOL.
I think when it comes to flirting and blurting, ENFPs fall into distinct 'yes' and 'no' camps. Some Fi doms/auxs seem completely oblivious to boundaries, social convention, what others will think. It's not a totally bad thing because it can make you fearless and give you an air of confidence/assuredness, excitement, or just that that good ole 'bohemian' vibe. LOL. However, it can also drive others crazy and cause a lot of personal problems for you.
I've heard on the forum a very clear line between ENFPs who say themselves they admit to being flirty intentionally or not and and those ENFPs who can't stand the idea or else are very consciously reserved in that area. Same for blurting.
My ENFP friend and I actually encounter this same issue with a mutual ENFP friend of ours. He just has no filter on his mouth and likes to get reactions from people. He can speak very thoughtlessly and I call him out on it.
Thoughtlessness/blurting out - it's also an ENTP issue. It's the Ne gone mad.
I think gender and age play a big role in the natural development of blurting as well. The older you get, the wiser. Also, guys tend to have the bigger mouths than the ladies and can get away with it a lot more. So blurting and making

comments is more an issue you would encounter with young male ENXPs.
There is also a line between ENFPs separating the blurters with the thoughtful to a fault speakers. Even when it looks like I'm blurting things out, I generally have already outlined or thought intensively about what I'm about to say and anticipated the responses, particularly if it's during a heated or important moment. I generally have always thought carefully before speaking (even if it's spastic, erratic, competing Ne/Fi fueled thinking ;P) and will not say something if I think it will pique someone or aggravate a situation unecessarily. Of course, I have my blind spots and moments, but in general I *want* to be thoughtful.
Personally, I find that trait of being thoughtless/self-absorbed and blurting things out with little regard for the other person's feelings or context or reaction to be real thumbs down! :thumbs down:
I don't know what you people are talking about. Every time you describe yourselves, you seem like perfectly normal social people to me. And I'm not even saying that to be nice,, I'm just being observant. The topic has been labeled "Issues" yet so far I've not seen any issues, except for the continuious stretching and pulling for (invisible?) facts in each and every one of your posts.
It's that damn runaway Ne, mang.
Actually, I thought the list was very good overall. Each issue doesn't necessarily hit each ENFP of course - there are a few I personally don't identify with - but overall it's a good general overview of problems with XNFPs. I think the list definitely applies to INFPs as well. Same functions, different order.
