Facebook is a linear stream and with so much unrelated material pretty much the only thing it's good for is talking about "now".

Forums are threaded discussions, keeping related topics in a hierarchical time ordered format.

Facebook generates so much garbage that it's worthless (as are all the rest). The ones that really make out are Seagate and Western Digital (Hitachi drive division) that make enterprise class hard drives since every bit of it is retained. Nothing on the internet is ever deleted. It just goes into cold storage (all hard drives). Drive guys love it. (I used to be a drive guy. One of the inventors of Serial ATA - SATA - and USB3.0 and the USB-C connector.)
