I a not here advertising social media, but I think there is no harm in checking it out by yourself and finding out first hand what it is all about.

There are accounts of Matt Graham of Dual Survival for example and there are several infographs of knots and shelters made by a poncho on Pinterest for example

It actually depends on what you are looking for. If you are looking for cooking recipes you will find them. If you are looking for stupid jerks, you will find them. If you look for business advise, you will find it. And so on
