4 simple steps to post a blockbuster
1: The headline is the key. Not every headline catches attention - user scan the page quickly and only titles standing out from the crowd are noticed. Make sure your headline is funny, unexpected, provocative and emotional - each of those qualities will help you catch user's attention.
2: Add an image or video. It should be related to the headline and confirm the original feeling that there is fun/something new/something interesting inside the post.
There is one other reason for including an image or video - the algorithm promoting the posts usually prefers those with media attached. Without image or video less people will see your headline and less people will have the chance to upvote you for your work.
3: Once your user becomes a reader, make sure that he is rewarded for reading your post. Be it a good laugh or valuable information, his expectations have to be fulfilled. Only then will he feel grateful for your effort and reward you back.
4: Your post should be short, otherwise users can be discouraged from reading it at all. Unless you're writing a scientific article, in which case Stemmit may not be the best platform for you anyway. Put your effort into making users lives easier, and they will do the same for you.
