How we rank

Rank is the number of separate people who recommend a product in a Hacker News comment over the past year. Someone who praises the same sync engine in five threads counts once.

The badge goes to sync engines that at least 10 people recommend, with recommenders outnumbering critics at least 2 to 1, recommended in at least 4 of the 13 months.
