I am to be found on both forums and they are very different in their outlook.
Grannynet is less inclined to discuss controversial topics I think, and will very often close down a topic that would not cause a batted eyelid on this forum. Religion, same sex marriages etc. - these are openly discussed there by some, but then others feel the need to ask for the topic to be closed.
It is interesting that grannynet seems to have more churchgoers, particularly catholics.
However I do find it an interesting place to be and at times have received useful advice and support.
It does not have the same open-mindedness as this forum.
