First of all welcome to steemit, I am personally here only for a few days so I don't really know how to answer all of your questions.
I upvote and follow people that share the same interests as I do and posts that I find interesting.
Works fine for me atm...
It looks like you're doing fine too. I'll have to start sharing more of my interests here in my posts. Thanks for the welcome and the feedback. btw @nativzel I have a friend who is going back home to his wife and family in El Salvador. He's been working here in Canada and sending money back home for years now.
