Hear hear!

I've used Greyhawk, parts of the Forgotten Realms, and various homebrewed worlds for years, all of which exist in the same planar continuum (usually).  The homebrews matured over the years from being Beleriand/Moorcock/GH rip offs to Mendenein, my "full-service" campaign setting.  Mednenein is a sister-world to Greyhawk (they're planarally close in the same way that Corum's Ghost Worlds of the ghoul-like halflings are), and both share some NPCs and organizations (the Hierarchs, for example), often with similar (or different ) agendas.  Mendenein also shares Oerth's two moons, and has a few others too (the number varies by season/year; some have very long periods and are "away" for a long time, and when they return they're more like the plague moon from Warhammer FRPG).  

Planescape was one of the hallmarks of 2e that turned me off from the game:  the cant in particular, but I never really got into the Blood War concept, which was too simplistic for my tastes, and seemed to set up the forces of evil to be very checked by one another and left good with too-free a hand to run the multiverse.  

I do enjoy the feel of the classics, but I only tend to use modules about 40-50% of the time, and when I do I tend to change them lot.  N1 is a good example---Orlane became a Lovecraftian backwater; the town cultists were replaced with woshippers of HPL's mythos, while the trogs of the town and dungeon became deep ones.   The dungeon had a shoggoth added in, and an EHP (for whom the naga was the chief henchman).  The NPC mage was kidnapped and sacrificed after the PCs grew to like and trust him, so he wasn't around to save their bacon at the conclusion
