Hello, I'm Daphne, a platinum member and contributing writer.
I have some thoughts on your new coin tipping system. In general, I like the idea of the coins; it's another form of validation. I shamefully confess that I obsess over likes and comments that mean nothing.
You should consider giving a few coins to new stories, and maybe some extra coins for popular stories and contest winners.
The writing drives your traffic, leading to revenue. The writers receive nothing for contribution, and a small something would lead to more stories, thus more traffic, leading to increased revenue. A complete cycle.
I assume the coins will have similar value as Cam-girl tokens, (I have a friend who is a Cam-girl) and don't amount to much individually, but add up over time.
If you don't write, you don't understand the small thrill that likes and intelligent comments provide. At least to me, and the coins will add an extra layer.
I am financially comfortable, and will redistribute any coins, if and when any are given to me, but others are NOT so lucky. Ten bucks means a lot to some, if not most people. I will probably purchase coins myself, to distribute for excellent work.
On a side-note, a boolean search would be REALLY nice, and is simple to implement. That's a search that includes 'if' 'and' and 'not', using '+' ',' and '-' signs. If you code in C or C++ I would be happy to provide the operative syntax. If you code, you know that already, so nevermind. …Daphne grins.
