Posting to a blog is a great way to say something individual to other people in the community. Use a blog to express an opinion, call attention to something noteworthy you've seen (such as an article on the Internet), or make a proposal. Other people can comment on your blog posts, so that a blog is a great way to pitch ideas that could impact the team or the company. Of course, you can comment on posts, too.
Your community might include several blogs, each allowing posts from specific people. For example, you might see "Bill's Blog" (with posts from Bill) or "Human Resources Blog" (with posts from people in the HR department). Your administrator creates personal blogs, associating them with particular people. If you've got something to say, get a blog going!
With blogs, you can:
To view blogs, go to the home page and click Blog Posts. To post to your blog, click New > Blog Post, select the blog you want to post to, then click Create new blog post.
To start a new blog post, click New > Blog Post.
