These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: You've Got Mail
"Funny Aneurysm" Moment: Looking back at this film with all of the documentaries and knowledge about being careful with strangers online is very sobering. True, neither was putting any overtly personal info out there, but with modern knowledge of internet scams and predators the sheer casualness of meeting someone in a chat room and talking to them immediately feels weird.
On the other hand, their relationship is pretty similar to how people whose relationships start online work. (With less romantic comedy moments of course.)
Genius Bonus: Thanks in part to all the main characters being quite literate, the dialogue offhandedly contains references to Anthony Powell, Mrs. Patrick Campbell's literary affair with George Bernard Shaw, Generalissimo Franco, Julius and Ethel Rosenberg... and The Godfather, of course.
Idiot Plot: Averted. As Roger Ebert points out, just when it seems that "a word from either party would end the confusion," the film throws a curve ball by allowing Joe Fox to figure out Kathleen's identity, which presents a whole new set of confusions.
