Hi! You can learn what hashtags to use, we can have 5 in total and the first one choosen cant be changed, but the rest can, and also you can add new ones on with the edit button (up to 7days one can edit a post)

If you find other writers, which there are plenty of, find their post and see what hashtags to use, there are many groups on steemit, like poet\writing groups, and then yeh, use the same hashtags as what others are using. Im not really part of a group on here but I see how it helps people make connections and get more upvotes by finding the right hashtags :)

If I remember or see any I will let you know! In the start I was using #minnow or something like that , #minnowsupport is another.. Like I say, I'll be sure to let you know :)
