I keep receiving this fatal error upon activating your plug-in:
Fatal error: Call to undefined function curl_init() in /var/www/blog/wp-content/plugins/twitter-blog/twitter-blog.php on line 338
It puts my entire admin panel out of action. As soon as I removed twitter-blog.php by FTP the error was resolved. I recently had Twitter Tools plus Twitter Tools: Bit.ly (separate author) installed but deactivated and deleted before installing your plug-in.
Wickett Twitter Widget is still installed.
