That is actually not a positive sign. With viral growth, we should observe rate of account signups increasing exponentially. If you consider the 85% abandonment of accounts which I documented, this looks like roughly in the realm of replacement and not significantly growing usership.
Without going into the number details again, like discussed with @jako before (I could not reply to his last reply, but let’s agree to disagree :) ), my post aimed to highlight 2 points, first the big growth in new accounts comparing to the past few months, and the democratization of a crypto based project beyond the usually closed crypto world.
I think Steemit has a very positive momentum now, which will probably yield positive results.
