"I hear that my web browser and email client can leak information or make my
computer vulnerable with things like cookies, JavaScript, Flash, and applets,
even with strict filters in place." Rather than integrate a full browser to display messages, Syndie avoids the
browser's vulnerabilities by implementing simple rendering itself. This means
that Syndie only supports rendering things that are known to be safe.
