How to delete recalcitrant tweets from Twitter

It’s easy to post something stupid to Twitter in the heat of the moment, but how can you get rid of it? In theory, you can delete any unwanted Twitter posts you’ve created by clicking on the delete icon next to them, but sometimes Twitter’s notoriously picky API gets moody and doesn’t want to help. If that happens, don’t despair.
First, find the nine-digit status number of the message in question by
going to twitter.com/yourusername and looking at the time stamp (’x
minutes ago’) of the offending post. The end of its URL will be a
nine-digit number identifying your post. Then enter this location into
your browser, replacing 123456789 with the status number:
https://twitter.com/status/destroy/123456789.xml
Twitter will ask for your username and password, and then you’ll likely
receive an error message saying the XML file doesn’t have any style
information. However, if you go back and check your history, you’ll
find the tweet with that number will have been deleted. (Thanks Paul M.)

The answer is there for anyone who can be bothered to search through seven months worth of posts.
Cool, but how do you delete twitter posts from services like summize.com (this is not an advert. I actually need to know, ’cause I’ve said some stupid things and summize keeps them)
This hole seems to have been plugged. I doesn’t work anymore.
