I'm actually serious. I am a newbie who just went to London and Paris. My photos are no better than if I shot with a camera on auto. I shot in manual or aperture priority
Basically my pictures are dull. I shot with a 2.8 17-50 lens and a 35-106 3.5/4.5
The cropped sensor made it very hard to get wide angle photos.
The photos as shown on the LCD screen were not the same as on the computer.
I know I'm vaguely ranting but does anyone know what I mean?

I think I've found your problem. As a newcomer to photography, I can sympathize.
Here are a few basic things that I've learned which may help you:
Photography is Light
Exposure is the collection of light by the camera. Nothing more, nothing less. Your camera uses the Exposure Triangle to determine which exposure settings it needs. First it does metering to determine how much light is in the scene and how much light it needs to make a 'well exposed' photo. In program mode, the camera will do its best to decide each of the three settings (shutter speed, aperture, ISO) that it needs. In the other modes such as aperture priority, you decide on one setting and the camera will choose the others. Except for manual where you choose every setting yourself, your camera will always arrange the three settings in a way which will give you a good exposure. Everything moves in 'stops' or doubling and halving of the numbers. If you want the same exposure (which the camera will always aim for) you can't change one number without affecting one of the other two. In your other thread, you ran into trouble because you were in aperture priority and you set the aperture to a fixed number. This meant the camera could only change shutter speed and ISO to get the shot you wanted. Although it seems that you actually had auto-ISO turned off which meant that the only setting that could take the hit was shutter speed. Shutter speed went to an alarmingly-low 1/13th second and resulted in a blurry shot. If you don't have enough light to work with then you either need to make your own light (with a flash, external light, etc.) or give up and forget the shot. If you're shooting in raw (look it up) then you may be able to under-expose the image and pull a bit of detail back out of it in post, but it won't look like a well-lit photo.
Manual Isn't As Useful As You'd Think
The only photos I've taken in manual are of the moon. And I actually had to do a bit of research before I tried it. M doesn't stand for "Master of the Universe" and it doesn't make you a professional. If I need DOF, I use aperture priority. If I need motion stopping or blurring, I use shutter priority. If for some strange reason I need to control both at the same time (almost never) then I'll switch to manual. It's also worth mentioning that manual doesn't work the same. The camera will not help you get the best settings. It will usually tell you if you're over or under-exposed though. Check your manual.
It's not the Camera, Sort of
Your camera will not make you a good photographer. Better cameras will give you a technical advantage, but they won't make your photos any good. Buying a DSLR isn't a substitute for studying the basics of both exposure and composition. Good photographers get better results on cell phone cameras than your average person can get on a high-end DSLR. That being said, if none of this is news to you and you already know all of this, your camera may be limiting you. I'm not sure of the low-light capabilities of your camera, but perhaps they're just not good enough for the types of places you take pictures?
What no Camera Can do
The camera can also only do so much. Its job is to capture an image of the world as it sees it. It just doesn't see like you see. It doesn't hear, see, smell, feel, or experience any of what makes the scene memorable. Human perception is altered by experiences. Camera perception is not. It also doesn't have the dynamic range or low-light seeing that you do. Shoot in raw and then in your raw editor you can make the image a perfect representation of what you shot. Or at least make it look better than what the camera saw. The truth is that nearly every image needs to be altered in post. That's just how it works out. For example, I liked the way my shots of the moon turned out, but I still needed to go back in post and drop some of the black out of the sky and add a bit of contrast to the surface. That's just what it takes to recreate the vision that you have.
