Only on MBTI forums do people mistype as Ns very frequently because they see that N is valued. My college required the MBTI in intro seminar courses, and I would say N/S is not confused as often as some here might believe. I mostly see ISFPs mistype as N which isn't surprising considering that many have strong Ni and participate in areas where N is looked upon highly, such as the arts. If anything, Ns mistype as Ss, especially SJs, because being organized, down-to-earth, and hardworking are prized traits.
I'll agree with heart, especially on J. I/E in a close second.
However, people mistyping others is a completely different topic.
When it comes to myself I find the N/S is most difficult. Probably because I frequently test as an ISTP, though the deciding factor was reading the overall profiles for the type and finding INTP was a much better match.
When deciding others types I'll agree that picking up on an N/S difference is difficult (compounded perhaps by being online) to do, for me noticing a difference in T/F is a bit more obvious.

And a woman screamed, and the lights went up, and two men lay stiff and stark...
Definitely the I/E divide. I can act like the biggest extrovert around a few people that I know very well. But put me around many people I don't know and I can actually feel the energy being drained from me.
Also, there's the confusion of introversion vs. social anxiety. Of course we know that extroverts too can have a lot of social anxiety.
