If I install and run WordPress from a subdirectory (as described here) will my post URL's look like this:
Assumptions: Permalinks are active and post name is "Hello World"
Oh, and another assumption - WP is installed in a subdirectory named "wordpress."
No, it depends on how you configure your site in the general settings. If you set your Site URL to http://example.com and configure the permalinks to use the name of the post, it will show http://example.com/hello-world.
Have done an installation to a subdirectory this weekend (http://www.myfilmviews.com) and as you can see, you can't see it's been installed in a subdirectory.
Nice website, by the way....
