I noticed the same thing. There is no change in Steemworld so the Steem block chain is not effected, but under Steemit, my followers are up almost 100 and my following count is almost up 200. On December 3, there was a similar glitch that went the other way. The joined dates are invalid too.
estimated account value gets fixed. now this.
It's wrong again but the start dates have been corrected.
ditto.
The follower and following counts and the joined date are normal again.
All normal.
