Hello and welcome to Steem. It can be a bit confusing to get started with all the options and information flying your way. Take your time and don't get disheartened by the lack of post rewards after your initial intro post, that can be quite normal. The Steempeak front-end as nice functions for writers and set up Keychain to secure all your keys. For mobile Esteem is quite good and the Tribes are a great way to direct your content to those most interested, you can also earn other tokens as well as Steem by using their tags. (just some tips to get you started)
Wishing you a happy stay here and really enjoyed the word flow of your intro. ( A bit more alliteration for you)
