Hints and tips for better photography

I've come to the conclusion that I've blathered too much to my friends about photography. Since I took it up as a more serious hobby, lots of them have been revealed as closet shutterbugs, or it seems that way, anyway.
I don't quite know why, but I keep getting asked for advice. It's rather flattering. Though I'm not at all convinced I'm really in any position to give advice. It's not like I've had a picture published, or sold anything, or exhibited my work, except at my website. Sorry, obligatory plug.
Anyway, partially as an exercise for myself, partially so I don't keep repeating myself and partially because it might come in handy for my City & Guilds course, I've put together the following list of hints and tips, that I've gathered and gleaned from many sources over the past couple of years.
Example photographs Take more photos - This seems to be the single most important thing you can do to improve your photography. However, there are a couple of caveats.
A bad photograph Be honest - If it doesn't work, admit it.   Don't over-critisize - Admit it when it has all come together. A good photograph
Camera Learn how your camera works - The better you know your equipment, the more time you can spend on the creative aspects: viewpoint, compostion, etc.
Thirds Be aware of the "rules" - There are a number of rules suggested for good composition. (thirds, level horizons, simple backgrounds, etc...)
I think it helps to be aware of these, but don't feel they have to be followed slavishly. If anything, they're only suggestions of things that might work in certain circumstances.

famous photographers Become familiar with the work of other photographers - Find artists whose work you enjoy (or hate) and try and work out why you like it (or don't). Avoid trying to copy another artist's style, but be aware that you can learn from other people's images, even if just to say, "I'd never do *that*!".
moving around the plaza of nations, vancouver, BC. You have feet, use them - Move around, try different viewpoints. Remember that you can bend your knees, or lie on the ground, or stand on a chair to change your height. (But be careful about it. Personal safety should always come first.)
studio abstracts You don't need exotic locations or good weather - Different days and locations suit different subjects. A little forward planning can help. Or try "studio" work on days when it's too nasty to be outside.
Example crops Crop, crop and crop some more - Crop in camera, crop on enlarging. Make your picture punchy, by removing extraneous details. Example crops
