In all honesty the best idea would be to concentrate on getting to know the community, perhaps find some kindred spirits with your shared interests, I've been here little more than 2 weeks and only recently started finding my niche. Also highly recommend reading up FAQs and intro posts on what steemit is about. I know I am not answering your question, but really, just post stuff on here, use reasonably logical tags, if it hits, that is amazing, but also don't get discouraged if it takes a while to pick up some steam (and steem to go with it), I promise the community itself has a lot of amazing people that make the stay and learning experience a breeze and the rewards system is really just a cherry on top! That's my 2c at least, take it with a grain of salt. Cheers!
