Most of the books/short stories I've posted here on TNBW I've also posted on Booksie. So, in my case, no duplicative efforts need me made. I, too, have noticed the slow pace of postings on Booksie. It seems a lot of new accounts are being created every day, but none of them seem to be posting--or reviewing--other's works. The 'number of reads' system seemed to work for a while, but I now think a lot of the "reads" are simply bots who jump from post to post, but never leave anything behind other than one more "read."
As far as enhancements go, I'd love to see a much better way of deleting your followers other than 10 (or less) at a time. A simple check box would suffice, then click a button that gets rid of all the checked accounts. I have gone back to my early days and found scores of people who left Booksie ten years ago and have never returned, yet, they still appear in my fan list. Looks impressive, but I like my account to be a little more lean and mean.
