I'd love to have this plugin be able to tweet about pages as well, like gallery pages. It could just take from the first line on the page for text, and use keywords, etc, like it does for posts.
It would be separate, so they wouldn't be affected by the date setting limiting the age of the posts. And it would have its own exclusion list and frequency.
Is there a simple hack to add this ability, I wonder? Anyone else interested in this idea?
