Dear Diary Example "Blog Contract"

In this post, i will be creating a Blogging Contract meant for Diary Entries and posts of articles or News.
Notice the use of "block.number" in this post as a way to see new blocks as they come in or get changed

contract BlogAresh {
    address public owner; 

    blog[] blogLogs;

    struct blog {
        string title;
        string headline;
        string content;
        string url;
        address owner;
        uint blocknumber;
    }
    uint counter;
    
    function BlogAresh() public {
        owner = msg.sender;
        counter = 1;
        blogLogs.push(blog("BlogAresh:", "My New Blog", "1.0","ethereumacademy.blogspot.com", owner, block.number));
    }
    //anyone can add a post to the blog (multiple writers)
    function addPost(string title, string headline, string content, string link) public {
        blogLogs.push(blog(title, headline, content, link,msg.sender, block.number));
        counter += 1;
    }
    //only the person who created the entry can edit
    function editPost(uint index, string title, string headline, string content,string link) public {
        if (msg.sender != blogLogs[index].owner ) revert(); //can do with a modifier
        blogLogs[index] = blog(title, headline, content, link,msg.sender, block.number);
    }

    function readBlog(uint i) public constant returns(string, string, string,string, uint) {
        blog memory l = blogLogs[i];
        return (l.title, l.headline, l.content, l.url, l.blocknumber);
    }
    
    function countPost() public constant returns (uint){
        return counter;
    }
}
