For the most part, I find the Macroderie community more helpful than the groups on FB I am part of. Usually on FB people tend to post images without EXIF data, and some are reluctant to share tips or helpful hints on how they accomplished their image. I don't find this on here, as most folk will willingly answer questions or provide tips.
I use both FB & Macroderie, but find most FB groups to be more of a showcase rather than a helpful platform for me.
