Trying to get the Blog to look like my site

The very quick and dirty way would be to dispense with themes entirely. It’s something I’ve always done – more for lack of time to themeize my site than anything else. What you can do is to put $wp_template_redirect = false; before your call to wp-blog-header.php. That will cause php to continue processing index.php looking for a wp rotor rather than looking in the themes directory.

I then use output escaping

ob_start();
…wp-rotor, etc
$results = ob_get_contents();
ob_end_clean();

to write the output of wordpress to the $results variable. I can then pipe that into my standard site wide template system. In fact I use output buffering several times to capture the various header and sidebar outputs.

It’s not perfect and I really should use themes, but I found that it makes wordpress easier to embed within an existing site.
