I see that User growth is stabilizing since around July 23; if you were to plot the first graph from that date (instead of June 29th) you would probably see a steady (not growing) number of new daily users.
Tomatoes by day (actual usage), however, is growing at a much quicker rate than users. This can only mean that part of the user base is actually using the service more.
