Hey guys, I'll share what I've noticed.
I never ask fellow authors to comment on the tracks, they always comment on they own.
Several items in my portfolio were approved at the end of April but the last comment was 27 days ago. Silence for a month.
Which means I've become less visible both for the fellow authors and buyers (poor sales in April and only 7 items sold this week).
Maybe AJ is working on the search engine again or just a lot of new authors come?
P.P.S. My answer's number is 12111, a triple can't lie.
