Hello @yvesoler, I am also wondering every time when about to publish a new post which tags I should use. I believe it is good to be specific. If you write often about biomimicry, use it for sure. I guess there will be more and more scientists here so it could be very useful for sorting them out. If you write an article which is "forest friendly" you can use our tag #forestfrinedlyfamily. ;) I also use sometimes #conservation. The rest of them you have already named them.
RE: Can you give me some pointers on how to choose what tags to use?
