Lightroom is used by many photographers and entusiasts
Also at the moment there isn't a "real" modern community where share photos, modifies and ideas: flickr is dead and old, 500px is very manipulated photos, instagram is low resolutions and is not adapt to post our works, Facebook is in a fall.
Discovery on Lightroom is beautiful to post our works and share the modifications, but it has not the possibility to talk with the other creators. So, it can be the first and the ideal place where you can share our photos, recive likes and it can be wonderful to have the possibility to COMMENT our and other works, or ask about a modify or the way to obtain a result or how the picture was made.
So I ask to take seriously the possibility to enable maybe via a flag the possibility to comment photos when we share it on Discovery.
It can be the real social of photography and the potential is enormous, is a killer feature .
