I always wondered why Facebook Home was scoring really low rankings in the Google Play Store. I thought it was a case of Android fan-boys all hating on Facebook.
It turns out that the Facebook developers were all iPhone users. Few if any of them actually used Android day in and day out, so they had no idea how important widgets and custom launchers to us Android users.
You’d think all those smart boffins at Facebook headquarters would know the No. 1 rule of making stuff: Know your customer.
