For people wanting to use hashtags to allow people to find their posts, I checked recent tags for art/photography related posts to check frequently. Including one of the ones that are getting more use will help people find you.
Tags with recent posts:
#photography 16
#cosophoto 1
#art 5
#cosoart 7
Also, if you post a lot of art/photos where the visual is the whole post, consider that we have at least one blind user who may chose to filter posts with a tag rather than mute you altogether.
*internally debates with self whether to tag everything with "paintedladies" from now on*
I've been championing everyone trying to add the simple #art tag to any art related post from any genre. Maybe we can make that tag a universal one to bring the whole of the Arts Community together to support each other, regardless of what genre we create in or even just lovers of art. We can help everyone get more networked and supported.
