Happy to go with a paid option
I like PWAT but they have ads all over the pages that my customer sees.
The thing I like about PWAT and mainly what I'm looking for in a paid script is that you can set the page that you're visitor tweets about different than the page they are actually on.
For example visitor goes to the homepage of my site which is a squeeze page and optin for my free ebook then they go to a page telling them to check their email. That page also tells them that they can get an additional bonus by tweeting about the ebook on my squeeze page.
They just click the pre setup button that already has a pre made message and a link to the squeeze page then after they tweet (or share on fb) they are directed to my download page.
Any scripts out there that do that?
A really nice thing is that it works with wordpress and regular html sites
