Sorry, the numbers at the end are debug information while I was making the changes to the Reader Comments. They should not be added any more, indeed the window where they were added was approximately 1 minute! Unfortunately my PHP skills aren’t as brilliant as they could be otherwise they’d never have been shown in the actual comment!
If you need me to edit the comments, or if you’d prefer to just delete them, please ask, and the same goes for anyone else who might have comments with numbers at the end!
The numbers do relate to the connection the comment originated from, in the case of your comment, a proxy operated by AOL. You can probably see the same number if you look at the showMyHits script.
