Is there a generalized  and specialized writing ? I would think that you need to do specialised research on anything you write , any subject for that matter. Unless you are writing random stuff about yourself I guess everything else is specialised ..

I meant to select a particular niche to write about or just write about everything. A few writers select a particular niche to write on. So that is what I mean.

Specialized writing means to be an expert on a particular niche and generalized writing means to write on everything. 

A person writes about what he is more comfortable with. Some writes more often on a particular theme as they have more knowledge on those themes. Some like to simply share their random thoughts. It doesn't matter whether you select a particular theme or random thing. What is important is how much research have you done about your topic and how are you going to present those ideas.

Yes I got your point, I feel that we all have our comfort zone, few subjects are closer to our own thinking and we can write extensively on those subjects.. personally speaking, I try to write on all subjects possible

My niche is Art and Artists, their styles and modes of Painting. I can write and discuss on my niche.

Everbody have their own niche, like some may be following Politics closely and analyzing while other may be involved more in Stock trading. Each individual has his own interest which becomes a niche in due course of time due to their knowledge and experience gained.

I believe selecting a particular niche is important and at the same time it is imperative that each individual by default will be acquiring niche over course of time.

However if we are thinking to particularly focus, then niche is important to have and random writing is also preferable but as a proverb says "Dig deeper than digging wider" holds true and hence having a niche is crucial in life, not just in writing.

Which one is better, to write on a specific niche or on everything. What is the difference between them if a writer has to choose any one of them- write on niche or on everything?

One has to choose his or her niche and apply to the  the field in your hand.

It depends, If you are writing for a client who gives you an assignment, you have to write on it and so you might end up writing for various topics.

But if you write primarily for your love of writing, you can stick to your niche, your area of interest and your expertise. This kind of writing will let your creative juices running.

If you are professionally writing for others, you have to write on the topics your client wants you to write. This might be one specialized one or writing on varieties.
