A blog is typically a personal website that allows its author to share their thoughts and experiences with the world. They can be updated regularly, which makes them more interactive than a newsletter. A blog has the ability to draw in readers who are interested in what the author has to say, while a newsletter is typically sent out periodically and may not have as much of an interactive component. A newsletter can be more informative since it features a longer list of articles and is sent out regularly, which can be helpful for people who have busy schedules.
However, a blog is typically more personal and engaging, making it a better option for those who want to share their thoughts and experiences with a larger audience. Overall, both options have their benefits and drawbacks, so it really comes down to what the individual wants out of their website.
