I love having targets, especially if no-one minds if I miss them. I love my lingQ targets, it really points out the areas where I’m lazy and the areas where I’m just a bit obsessive.
What they don’t do is take into account when I started on lingQ. So my stats look good for this past week, but bad for the last fortnight. As I haven’t had an account for a whole fortnight that’s not surprising.
Personally I would also like targets that look ahead to the end of this week or month or year, and tell me what I still need to do to be on track for some point in the future. But I don’t expect you to redesign it all for me. Maybe if the page showed when I actually joined so I can work out for myself which historical timescales are meaningful for me and which aren’t?
