Yes. Mainly with INFJs and INTPs. I got to see more of the introverted side come out. Especially INFJs. I always got on with them, but never truly understood them, I still don't, but now I recognise it as a difference, rather than a misunderstanding.
INTPs I always knew were smart, but missed the wild side a bit. I like that evil touch. Well I knew it was there, but it comes out way more on here. I always thought INTPs were slow thinkers too, which is actually quite funny when you think how good they are at stuff. But I realised recently it is that they are more logically perfectionist. When I know I have enough to confidently answer the problem I stop, they take that extra time to perfect it. And I see why they think I am wrong often when I give answers to things, because I tend to only mention the things that are relevant to seeing the bigger picture, rather than fully specifying the problem.
I can now spot an ENTP and INFP too, which is quite important, because I know I can derail the conversation into interesting stuff even quicker

.
I didn't really learn what these types were from here though, just recognised them in real life and the combination between some things from here and real life improved understanding.
