well, i'm an interior designer, so totally bare walls throughout a home drive me batty. LOL! however, it really doesn't take tons of "tchotchkes" to make a house feel like a home. paint is the single least expensive thing you can do to a room for the most impact. are your walls painted or are they white? because that alone may help it feel more "decorated" to you.
my personal style is more on the modern/contemporary side with a dash of traditional/eclectic thrown in for warmth. there is nothing in my home that isn't meaningful to me or my family.....and i think that this is a really important step in the design/decorating process. nothing reads "generic" to a designer like someone rushing off to the store and purchasing the exact same room set up like the showroom floor. true design is a collection of items you love, purchased over a long period of time......or atleast "looks" that way.

you want to stay away from buying stuff to just fill a space. live with your empty space or bare walls and let the perfect items find you.
you are welcome to take a look at my home (which was NOT done on a normal interior design client's budget! lol! and it is not a showplace.....i LIVE here.

)....... here are some photos:
kitchen (which we just remodeled in january)
living room (which is one of the last rooms to get redone to a more contemporary look.....hopefully this year!)
dining room (was remodeled last summer) computer desk area (with old chandelier)
master bedroom (was completely remodeled from the end of 2007 into spring 2008)..... sorry there's a lot of these!

okay, so if you got through all that then i applaud you! lol! please feel free to ask any questions as i'm always happy to help out in any way that i can!

ETA: i am a major "purger". i HATE clutter. there's a fine balance between stark and "homey" and you need to figure out what that balance is for you, as it's different for everyone.
