Normalization / 3rd normal form in tables?

I am creating a small news website, and someone suggested I look at the normalization, which I did, and although I understand this, I don’t quite understand if this applies to all the tables in the database. For example, I have this “Articles” table, consisting of:

ID                      -   10001
Featured                -   0 or 1
Category                -   Category Name
Title                   -   Title For The Article
Article                 -   This is the article.....
Photo Description       -   Photo to go with blog 10001
Photo Name              -   John Smith
Photo Link              -   www.johnsmith.com
Author                  -   myname@gmail.com
Keywords                -   keyword, keyword, keyword, ...

Views                   -   600

Is there something wrong if you leave this table as it is, or should it be converted to the 3rd normal form?

EDIT:

What if I had:

**Authors**

email
name
avatar
bio
website_link
facebook_link
twitter_link

**Articles**

ID                      -   10001
Featured                -   0 or 1
Title                   -   Title For The Article
Article                 -   This is the article.....
Photo                   -   10001.jpg
Photo Description       -   Acts as alt tag
Photo Name              -   Crediting photographer
Photo Link              -   Link to credited photographer
Author                  -   Author ID
Added                   -   2014-07-27 10:41
Views                   -   600

**categories**

ID
category

**article_categories**

ID
article_id
category_id

It’s still hard for me to understand the reasons why so many tables are such a wonderful thing, although now there are many joins to be made. Why isn’t it easier to use php to say

select * from articles where category == $category

or

select * from articles where featured == 0

or

select * from articles where author == $author_idetc. etc.
