I have found that American accents are becoming more homogeneous, probably as a result of television. I'm from Texas, but you would never know it to hear me talk. No one here in Colorado can tell I'm a native Texan unless I "put on" a Texas accent. I put on all sorts of other accents too, like the Midwestern "Fargo" accent, California Valley Girl, Deep South, and New York accents. Accents are fun! 
Hmm another reason its becoming homogeneous as you say is as the Schools try and beat the accents out of the kids, plus regional dialects. Well least here they do. I used to be repreminded all the time for using the dialect I grew up around and used. And at first they attempted to drown out my accent by making fun of me or by use of public speaking. Funny enough that last bit backfired on them, as I knew how to carry my tone and thus was a very engaging speaker.
From spending time with various people and what not, more so my wife, I can actully hide or drown out my accent. But I do have one, Its kinda like Andy Griffin, just more Southern Gentelman too it. Whats hillarious is when I use it around people not from my region they love it. Here though people laugh at it. I can do some other Accents, very damn good Russian one, I actully fooled a Russian once with it, mainly other foreign ones though. But very few US accents. And when I was in pratice speaking German and Japanese, I could speak them with something of a native dialect, or so I've been told...but thats fallen so far out of use I remember so little of it. I can make the proper sounds and such for Mandrin and Cantonese but short of basic prhases and what my wife tries to teach me I don't really "know it". But I love accents, they tell you where a person is from, even Canadians differ. Meet someone from Quebec, Vancouver, and Albert, rarely will they sound the same. And by telling where a person is from or currently lives and a bit of geographic knowladge you can know a great deal about that person and what to expect to an extent culturally. People around here never understood my facination with such things, more so that I botherd befriending the exchange students.
You can learn a wealth of information if your not worried to ask, and listen. Funny enough I prefer solitude...or maybe its just the locals that make me that way.
