You will get a bit of spam for the introduce yourself tag but a few people might see it. Also you need to put some text into the post if you want people to resteem (share) it. Here is an example of an excellent (although very long) #introduceyourself post from one of the photographers here on steem. https://steempeak.com/introduceyourself/@derekkind/hello-i-m-derek-a-canadian-landscape-photographer-and-i-d-like-to-share-a-few-photos-with-you-and-tell-you-my-story
