Not only good, but daring!: With regard to your snarky post-script, I would say that "Friends" dared to be realistic in not bringing in the token minority to "round out" the cast. You know, the six whitebread Gen Xers and their keepin-it-real building Super (who gets to impart his Bronx-bred wisdom on the naive ensemble), or maybe the six of them and the precocious street kid from the streets who cracks wise on them as they enter "Central Perk" (that's the coffee shop where they congregate Eno).
The fact is the real people that led lives akin to "Friends" don't mix with the building staff; they don't acknowledge the street urchins, and if most of their friends are from college or even earlier, then they probably look, act and think just like they do. Putting in "persons of color" (although it was done in Season 9 with Aisha Tyler, who is very, very funny and smoking hot) would be the most blatant of pandering, and do more of a disservice than excluding them altogether (which was just about done). In short, "Friends" was the most revolutionary t.v. series since "All In the Family". There can be no debate.
Of course, some people share your viewpoint rather strongly.
