On competing projects, as journalists often like to ask Wikimedians about other wiki projects and encyclopedia projects with a "let's you and him fight" line of questioning:

We should encourage the success of other projects with compatible aims and goals to those we have, and hope their accomplishments will be to our benefit also. We should like to see other people taking a different approach, watch their progress, and learn from their successes.

(Unspoken subtext: if they don't have compatible aims and goals and aren't going to share content under a free content license, they can go jump in a lake, and if they have no successes from their approach we'll just keep on our merry way, but I'm not going to say anything to further a story manufacturing a feud.)
