Blogging is basically keeping an online journal to share with
others and has become increasingly popular in the past few
years.
If you choose to blog on your profile page here at our network, you
get to decide who can view your blog posts: just you, just your
friends, or everyone (the default setting). To change this setting,
click the "Settings" link in the box on the right column of
the page. Click "Privacy" and click the circle next to who you want
to read your blog. By default, your blog posts are set to allow
anyone who can read them to comment on them. You can change this
option and limit who can comment on posts to only your friends — or
only you. You can also decide if you want to approve comments
before they are posted or all comments to posted immediately. These
options are listed under the "Privacy" link under your "Settings"
as well. Finally, each time you write a blog post, you can override
your settings to further expand or restrict your audience!
Here's a short video that gives you an idea of how to best use
blogging to share your ideas!
