They say the first million is the hardest, and it's true: it took Jetpack 13 months to get its first million downloads.

However maybe doubling is easier. In the past 4 months Jetpack has doubled its downloads and flown past 2 million downloads from WordPress.org, tripling its growth in just a few short months.

What's putting extra fuel in the Jetpack? Updates, of course. We've shipped three major new feature releases that have seen huge adoption -- contact forms, Jetpack comments, and carousels -- in just the first half of this year, in addition to dozens of smaller features, and there is lots more on its way. (Maybe even something this week. :))

Any bets for when we'll reach 4 million?
