I believe you should have edited it out. It doesn't serve to enhance the post in any way. It's along the same lines of "Should 'Hi', 'thanks,' taglines, and salutations be removed from posts?"; for these things the community says overwhelmingly that they should be removed.
I believe that the following two points (referencing points #1 and #3 in the "community says overwhelmingly that they should be removed" link) brought up in that answer apply here:
1) It will leave even less room in the question preview so that we have more difficulty gauging what a question consists of by reading
3) If this is supposed to be a website which is servicing more than just the primary author...
In this particular case, #3 definitely applies, in that the statement serves no one but the primary author, and SO is a site meant to serve all.
