I've met very few other INFPs, IRL. I met one INFP guy once, and we went out on a date, and I did not like him. He was very self-absorbed and immature. In retrospect, he may have been ISFP though (based on things he said), but he tested INFP (it was on his profile).
I know many, many ISFPs and I like most, with few exceptions of ones who are too hedonistic and physically-oriented and some who are too aloof and grouchy.
I know a lot of ENFPs, and I like most of them. We're usually a good match as friends, because we have a similar mindset, but there's a nice E/I balance.
I do know an xNFP woman, who may be INFP, and we've always clicked well. She's very odd, and a lot of people don't get her, but I do. I can't decide if she is E or I though.
Online, I like most INFPs, probably because I relate to them in some way and that is nice (and unusual for me). There are a few who rub me the wrong way though, but it's more of an individual thing.
