How do I have a single post, and only let my closest friends view it?or
How do I keep people from commenting on some posts?or even
How do I make a linklist / poll / whatever visible to a select few?and the answer is - you can't.
If your blog is open to everybody, all portions of that blog are open to everybody. Unlike WordPress (which has a few limitations too, just not this one), you can't set permissions in just a portion of that blog.
But, you can make portions of another blog visible to a selected audience.
- Make a separate blog, with permissions that suit your need.
- Put the restricted content into the second blog.
- Include or link the second blog to your current blog.
Blogs are free. Setup another, with the restrictions that you need. And another, and another.
