To me #3 is the easiest to do. There are some that have no interaction with people who comment and they are losing out on the best part of the Steem platform, the relationship building.
#1 is where I really struggle. Trying to come up with a title that attracts attention is just something that seems hard for me. Not sure why, but I guess it comes with practice.
Exactly, just like with writing a traditional blog you should be wanting to build a relationship with your readers. And it's so easy to do. And yes, creating headlines is something you'll get better with over time. Once I started understanding the importance of headlines then I began really paying attention to other headlines out there. By seeing how headlines affect me (or get me to click) I have learned how to create headlines and titles myself.
