The problem seems to be that there is a limited amount of (recycled) information available for articles - or is there?
I first got into writing by thinking exactly the same - all the existing articles are boring and I could do better. So I wrote a few and they were all rejected - however I came up with an idea that was slightly different to the norm, it was accepted and I've had a few different articles printed since. It also pays to see what's topical at the moment.
I agree with some of you in that a lot of writing can be bad and editors can't get through all the stuff they're sent - however if you can come up with an original idea, speak to the editor first and they can give you help and advice.
A good original idea and you should be laughing and helping improve the mags!
