There are some great tips out there but as Chrismahon says, not all are good. For example, if you look up how to prune a golden gage
do not follow the advice given if you want to have a living tree at the end of it
Same for how to roo a sheep - there are some good clips, but there's one where the person should be prosecuted!
In general though I agree that the info out there is great. When we started out with smallholding 25 years ago, there was no such resource and no TAS either
so getting info in a hurry was almost impossible
