Share - Subject, Tweet do not reflect Topic title

When I use Share with Twitter or Email (and perhaps other options too), the tweet text/email subject always are "UserEcho.com -  Customer feedback 2.0 Creative ideas for Your projects". My expectation these would be The same as the topic I'm sharing?

If the above is "by design" and intended to promote UserVioce service, could we have an option to keep the "Subscribe/Unsubscribe" and "Get a short URL" options and turn AddThis sharing off?

Thanks!
