If you're new to blogging, one of the toughest challenges you'll face as you start your new blog is determining your blog's content. There are many different styles of blogs to consider. I'll discuss a few different types of blogs (and show examples) that may inspire you and help you overcome writer's block:
Travel and Cultural Blog - Blogs can be a great place to keep track of your adventures. There are a variety of blog formats that can highlight the pictures, videos, and reviews that you share about your trips. You can share travel tips based on your own experiences and make traditional "postcards" a thing of the past.
Example: http://everything-everywhere.com/
Reviews - "Review" is one of the most commonly searched for words online. This type of blog will allow you and your readers to share opinions about products, such as electronics, movies, music, video games, and more.
Example: http://blog.tradetang.com/
Fashion and Lifestyle - People are always looking for the latest trends and blogs are a great way to showcase them. From promoting good health and wellness, to sharing the most fashionable ideas and innovative styles; blogs can showcase your passions and create a forum for reference groups to collaborate.
Examples: http://vainandvapid.blogspot.com/ and
http://www.foodpolitics.com/
How To/Tutorial Blog - People are constantly searching for information online that shows them how to do things and this type of blog helps others learn. It's important that the writer truly knows how to develop a well-written post on a "how to" blog. This type of blog should be reserved for experts because a good tutorial post is often followed by lots of comments and questions from readers.
Example: http://ana-white.com/
Personal Blog - This is the most common type of blog. These blogs revolve around people's experiences. They can house a wide range of content and a variety of posts, and contain details about your interests and day-to-day thoughts.
