Use hashtags that fit to your posting and that are used/followed often. I for example follow some hashtags that fit my interest and see postings of people I don’t know. When I created my first posting I used only three of these hashtags and quickly had some favourites and shares. Also try to be active in the comments, they are the places where people can find you easily.
Am I the only one seeing Jabba The Hut and a Death Star in this picture?
