Some of my favorite Steemians currently are :

@steevc posts about life in general, and music.

@rebeccabe posts about life in general and photography. Fun person to follow too, she puts the social in social media.

@cryplectibles all about comic books!

I also think @leecamp from RT news is a great addition to Steemit. He posts a lot of political commentary with a humorous edge. Definitely worth a look if you don't mind a good chuckle about our current political atmosphere.

@kennethbosak posts about cryptocurrency, very informative and entertaining... Also livestreams on Vim a lot.

Those are some of my favorite accounts right now. There are so many great people on here, it's hard to just name a few.
