It took me a while to get the hang of resteems, but once I did, I've only resteemed posts that I actually value, and feel that my followers will value as well.

So far that amounts to once daily or less. I'm all for supporting the authors I like, but have no desire to spam, and dislike it when I am spammed . . . which is why I've pretty much deep-sixed Facebook and the rest of social media in favor of Steemit

That said, I think you're the only author to date that I've resteemed more than once. But, since you are posting specifically on how best to succeed with Steemit, I can't imagine anyone on the platform not being interested.

I must agree with @bethwheatcraft, however, that for me, following only ten people would create too much of an echo chamber, as I have extremely wide-ranging interests. I also like reading the opinions of those with whom I disagree, in addition to those with whom I agree, as I learn far more about the issues in that way.

But, like resteeming, I've only followed those whose content I actually value, so I look forward to their posts, and thus far I have never felt the need to unfollow anyone.

In the roughly fourteen weeks I've been on the platform, I've followed just over thirty people, which is a good number for me. I might get up to fifty over time, but doubtful more than that, and I'm getting more and more picky about following.
