Ask HN: Please review my Twitter search appendage

URL: http://twhittler.com/

Summary: twhittler is an interface to Twitter search that helps you "whittle down" search results by hiding tweets from any user you want.

I whipped this up after being frustrated at all the spammy or irrelevant tweets surfaced when I was searching for tweets related to one of my projects.

My questions to you are: * Is twhittler something that would be useful to you in your work? * Are there features I could add that would make it better?

Thanks HN!
