Sometimes links are useful but as an addition, not the sole answer. I use RHS links to give more info on a question I'm answering, such as pruning, as they have pictures or graphics which help explain things more clearly.
I run a garden group here with mixed nationalities. It's always easier for them if I can demonstrate in person at a meeting or show a link to a picture in a newsletter rather than expecting them all to understand what I mean by things like "prune just above a leaf node" or "prune to an outward facing bud". Some of them come from warmer climes or vastly different plant groups so haven't a clue about northern European gardening plants, rhythms and tricks but are keen to have the knowledge.
