Where these numbers come from
Every figure is read from the WordPress.org plugin directory's public API, and each page links to the entry it came from. “Most-installed” is the directory's own popularity order. WordPress.org rounds active installs into buckets, so “1+ million” can mean anything from one to two million.
These are the directory's numbers, not my verdicts. I haven't tested these plugins. Where I have checked a deal on one, its page says so and links the deal.
