You can now have Google Feedburner send tweets in addition to creating an RSS feed.
Assuming you have a Feedburner account set up at http://feedburner.google.com/
go to the blog you want to connect to Twitter and select the Publicize tab, then select the Socialize option.
It will let you OAuth to an existing Twitter account.
It tweets post titles along with a goo.gl short link.
See Using Socialize to distribute your feed on social networks for a bit more info.
Of course, be mindful that in addition to giving you granular stats, this also gives Google yet even more information about how people engage with your content.
I didn't want to mix blog post tweets in with the rest of my account, so I made a separate feed
The Socialize feature is also related to an upgrade of Feedburner, it now has a new (apparently optional for the moment) interface that can provide real-time stats
See Google's blog posting Your stats, right away for a bit more info.
