I love the feedback from e-tools on Weigh In Day. If you lose, you get a nice little message, and if you gain you get encouragement to look back and see what you could and couldn't change.
That's one think I like that Sparkpeople was missing for me. It never gave me feedback on weigh ins, whether I was up or down. It was just that same lady holding her scale up.
And I like that I can put notes in at each weigh in so I can scan back and see what worked and what didn't.

(I lied - I do like it!
It means I'm losing!)
YAY!
