 * While looking through the source of my site I noticed something quite disturbing
   from a security standpoint. The All in One SEO plugin puts the version number
   in the source of the site. From a security standpoint this is a big no-no, you
   don’t want people to know the version of something you are running. If your version
   is outdated and there is a known security problem it is much easier for a script
   kiddie to exploit.
 * For my personal site I changed the following code:
 *     ```
       echo "\n<!-- all in one seo pack $this->version ";
       if ($this->ob_start_detected) {
       echo "ob_start_detected ";
       }
       echo "[$this->title_start,$this->title_end] ";
       echo "-->\n";
       ```
   
 * to
 * `echo "\n<!-- all in one seo pack -->\n";`

 * Ahh, forgot to redirect all of the various feed items to feedburner. Still trying
   to work out all of the oddities of WordPress after moving over from Serendipity.
 * Command line is fun:
    tail access_log | grep 199.[0-255].[0-255].[0-255]
 * Thanks for pointing that out.

 * Hi Zac, I don’t think I will leave the version out because it helps me tremendously
   in diagnosing problems (which I do every day). And there has never been any security
   problem I’m aware of. So the benefits outweigh the drawbacks IMHO.
 * If there is a loop hole in a web application you don’t care very much for the
   exact version anyway since it’s so easy to just probe it automatically.
