Yeaaaa… but it’s also a bit like saying: “Which is better? An excavator or a shovel for gardening?”
Some will say the excavator is clearly superior since it can easily dig out and move 1m3 of dirt in a single move and easily 20m3 in half an hour. However, that also means the excavator is a total hassle if all you need is to plant some roses in the garden near the patio. Here a small garden spade is without doubt the best.
Facebook isn’t one particular functionality, it’s at least 200 use cases easily. But each one of the (at least the ones most frequently used) still has to be cleanly and minimally designed.
