Thanks for stopping by, I'm glad you found something interesting here. I would expect your numbers to be at least one bit higher than just a few percentage points. Remember, if somebody upvoted a single post in the beginning of January, followed me and I never heard of them again, they still count as an active follower by the standard I've used to compile the stats.

I think there are very different people here in the way they handle their feeds. There are some seasoned steemians who curate their feeds very carefully and make sure they follow only people they really want to hear from. A follow from a person like that is indeed worth a lot and the simply follow and feed system here works great in that case. But there are also people who simply follow everybody to get a follow-back and this is dead-weight padding on the number. That's why many people on here call the followers count a vanity metric.

The only thing that I think is wrong with the feed here (cause I like it unfiltered) is the fact that if you post at regular times of day, a follower from a different time zone who is usually asleep or otherwise engaged at the times you post at might miss all of your content.
