A few months ago, I think that the WSJ ran an article on this topic, especially focused on suburban bedroom communties.  After working and commuting all day long, people were just out of time and too tired to spend time on social networking in their communities.
And then there are your own kids and relatives to deal with...very little time for friends these days.
I live in an old mining town; guys would work hard in the stopes and shafts all day, have family at home, and still had time to support a lot of bars and churches.

But then, back then there was no TV, internet, or stereo systems.

Sure sign the housing bubble is bursting

Flip That House

Coming on Thursday, July 14, at 9:30 p.m.!

House flipping -- buying and renovating a house to sell for profit -- is currently the hottest trend spreading through the real estate industry. A "flip" occurs when an individual purchases a home, remodels the home in a short period of time (anywhere from 3 weeks to 4 months) and then re-sells the home for a profit.

Flip That House is a new series for Discovery Home that dives into this very craze. Each episode is a fun, fast half hour that will document the entire flipping process of one house.

A perspective on flipping:

Flipping real estate by John T. Reed

John  T. Reed is one of the few real RE gurus. Yeah, he uses that term too lol! His page is worth reading, every word, ever review, everything. His newsletter is pennies compared to buying a house, and probably well worth getting too - I read the sample copy and it's up to date on reality not RE agent propaganda.
What's really funny is that show premiered last year.
My how things have changed since then in the housing market.
A few months ago, I came close to buying a condo in the suburbs. Why I decided against it was a lack of bars in walking distance. Bars are my mode of choice for being at all social, sub-optimal as it is. But it's better than nothing.

And that's the problem. The suburbs are about like a lunar colony where the homes serve as habitats and the cars as the spacecraft. You can't walk anywhere in the suburbs any more than you can walk on the moon without a spacesuit. That's becuse everything in the asphalt desert is too bloody far away. I lived briefly in the suburbs before what seemed to be a mass extinction of bars. Now, it would be some lonely stuff out there.

Why the mass extinction of bars? The automobile is a good suspect. With DUI being dangerous, and fiercer crackdowns to get these morons off the road, people gave up on going to the local bar. So, they close up.

It's little wonder the coffee shop cropped up. But people are too busy to socialise there thanks to laptops. Also, if you're already an insomniac, a coffee shop is a poor choice anyways even without laptop proliferation.

Maxout this is where you really need to read Kunstler on the evolution of US housing, the house with no garage at all unless it was the house of wealthy ppl then it had a carriage house in back. When cars evolved and started to displace people at the dominent US life-form, you first had houses with a garage in back, small and almost out of sight, to a larger garage about the same distance from the curb as the house, to today's "snout house" with the garage right out in front, and the front door almost an afterthought - which after all an entrance for people would be. The people only seem to exist to support the cars.

I wish I could find this..... in the 70s they had a 2nd version of The Mickey Mouse Club show on TV, with some neat re-runs of some of the funkiest Disney cartoons, one was about cars, and was from a sort of "space alien visiting Earth" perspective, it was eerie, the space alien's conclusion was that cars were the dominent life form and humans seemed to be a sort of parasite on the cars.....

I hate the garage in front of the house design.  It's ugly, IMO.

However, there is a reason for it.  The garage is put between the house and the street in order to shelter the living space from street noise.

Unfortunately, what it proclaims to the world is that "Cars Live Here!"  
The actual human-occupied portion appears increasingly secondary, little more than an add on in the back. An architectural nightmare.
The importance of the automobile in US culture cannot be overstated.
Well, in detached housing the alternatives are garages in front, or alleys in back.  I think in general I like alleys less ...
And garages are often huge today.  Three, four, six bays and more.  Craziness.  I know people who have two-car garages at the front of the thouse, and build another two or three bay garage in back.  

Personally, I'm fond of the "breezeway."  A little screened or windowed porch that connects the garage to the house.  You can sit out there in summer, and put the beer there to keep cold in winter.  :)

My parents' garage is in back of the house, connected to the kitchen.  But I think that's partly because of the association rules of the subdivision they live in.  You cannot leave your garage door open if it can be seen from the street.  So people turn the garage sideways and put it in the backyard.

Chris Alexander in "A Pattern Language" makes a strong case about doorways, transitions and entrances. No, the garage is there first and foremost because that is how people come into their home. It IS the front door. It's not there to block noise from the street. I'm one of those Mainers with a garage too useful to park a car in - in other words it's full of trash and treasure. My ex lives in one of those developments where cars have to sleep in the garage. That's her front door, an oil-stained concrete slab. I have to walk outside past the roses, peony and herbs. Sometimes in the rain.

My bike, OTOH, lives in the house, in the front entryway. Hers is hanging up with flat tires in the garage.

I thought the front door were the one intended for visitors. Seems lonely to have your garage as the front door.

Its quite common that a door closer to the kitchen is the most used door even if it isent the front door.

Cultural difference?

Is not Starbucs etc an example of exactly the kind of trend needed to create more social meeting places? Even if people are bringing their lapatop "TV" with them, its a lot better then staying at home. Btw, I realy should take my laptop to a coffe shop. ;-)

And I prefer insomnia before alcoholism any day even if both are realy bad for your driving.
