A blog is a personal website where an individual can share their thoughts and experiences with the world. When writing a blog, the blogger has complete control over what content is published, and can also choose to accept or reject guest posts from other bloggers.
A portfolio is a collection of work that an individual has created over a period of time. A portfolio can be divided into three categories: creative, professional, and technical. A creative portfolio contains work that is outside of the normal scope of an individual’s professional career.
A professional portfolio contains work that is within the scope of an individual’s professional career, but may not be as creative as work in a creative portfolio. A technical portfolio contains work that is within the scope of an individual’s professional career, but may not be as creative or as visually appealing as work in a creative or professional portfolio.
The main difference between a blog and a portfolio is that a blog is written by the individual who owns it, while a portfolio is managed by someone else. A blog is personal and allows for greater freedom in the content that is published, while a portfolio must adhere to specific guidelines set by the owner.
A blog also allows for greater interaction with readers, while a portfolio does not typically allow for direct interaction with viewers.
