Blogger.com has offered free blogs since 1999. With a nice feature set and clean interface, it quickly became and has remained one of the most popular blogging sites online.
Blogger offers several features that will help build a community around your site. Site-wide commenting allows any visitor to post thoughts and feedback on your posts, and you edit and delete them as desired. Blogger also allows you to control the access of a group of users, allowing several people to contribute to or share a blog. This is a great way to have guest writers on a site or build a group blog centered around a topic or event. You can also join the large community of bloggers also using the free service, by making your profile public and finding people with similar interests.
Blogger allows you to completely control the design of your site, from choosing a pre-made template to redesigning the site with your own graphics and code. This flexibility is a major selling point as you can have a blog blend with an existing site and make the Blogger brand virtually invisible. If you choose to use a Blogger template, their drag-and-drop system allows you to customize the look.
The Blogger interface is extremely simple, allowing for quick and easy posting of content. Easy photo uploading lets you add pictures to blog posts, and you can even send posts and images directly to your blog from a mobile phone, allowing you to blog from almost anywhere.
The sign-up process for Blogger takes you step-by-step through creating your blog. Since they are now owned by Google, a Google account gets you into Blogger. You then name your site, pick an address (something.blogspot.com), choose a template and get started.
