What you get out of Gransnet depends on what you are looking for.
If you come from Mumsnet you will be used to an argument or two. You will find those soon enough - the political threads are usually good for a workout.
If you prefer a friendly chat about this and that, with no stress, go to Soop's Kitchen thread (Soop is a real person, who started out as Supergran and opened the Kitchen as a refuge for those who had had enough of verbal fisticuffs.)
In between are threads on all kinds of subjects, from relationships to sponge cakes to gender swapping. Wander about the topics and see for yourself.
