what can be done w a histogram?
what value does it have?
I see it for each pic but have no idea what it is used for or how it can be useful.
I know what the histogram is and what kind of information i conveys but I don't find it useful like many others.

Okay, you've got me stumped! If you truly know what it is then why would you be asking this question?
Also, many other "what"? Other systems like meters or gages and equipment or like other people do?
Histogram shows the tonal range you have captured from white to black and if you are over or under exposed.
Read this article and you will then understand the histogram.

BebuLamar didn't ask the question!

Sorry about that. Forget my last. Some how it showed up as one message on my cellphone. Now it shows up with a commercial separating to two.
Reasonable explanation.
I use the Lightroom histogram when processing. Use contrast to spread out a bunched histogram, exposure to move the peak, the white slider to adjust the right side, the black slider to adust the left side.
I don't use it when shooting.

Let alone attaching the word "smart" to the terminology.

Yeah, that is dumb, isn't it?
Are you referring to the live view histogram or the in camera photo review feature or a histogram on various photo editing software? If you don't want to see it when reviewing photos on your camera you should be able to turn it off in the setup menu of your particular camera and also in your editing software. If you want to lean a bit about the histogram do a google search and you should be able to read for days the opinions of others. Rather than wonder what its usefulness is do some research, you might learn something new.
BTW, Histograms are just a reference they aren't Gospel. Depending on what you want the photo to convey the histogram could be totally different for several versions of the same basic photo.

In-camera histogram is something I do not use often, but when I do, it is for either of these two things:
1. To get a rough idea on how much exposure leeway I have between under- and over-exposure.
2. To determine if there is possible clipping on one of the color channels - when shooting very vivid objects, such as flowers.
On the other hand, I find the editor's histogram to be an extremely valuable tool when adjusting filter parameters, particularly when manipulating contrast and saturation levels. The histogram often tells me more about what's going on than simply looking at the image.
