Script Summary: Shows a Flattr-button for all tweets and on user profile pages.
This is what it looks like:
It is now possible to flattr Twitter users or individual Tweets.
The current version of the script (starting with v1.0) uses the new static Flattr API, so no search requests are made to the Flattr.com servers to include the button. Only a single request per page load is made to download the small Flattr-icon.
Now works with in Firefox and Chrome. Safari and Opera have not been tested...
I would be happy about reports concerning Safari and Opera compatibility. I can't test Safari myself since GreaseKit is not available for Safari on Windows and Opera did not want to run Userscripts at all for me...
