My personal opinion on people trying new 'standards' of roleplaying is [b][i]Go for it[/i][/b]. I can't stress that enough, we only really improve through trial and error experimentation with our writing; although not everyone is always necessarily after improving their writing. It's personal preference for how they enjoy their roleplaying but the main thing to do is that if you have a go, be prepared to put the effort in and stay on the right side of the writers around you.

My personal standards as a roleplayer are really quite snobbish; I know there's the old adage of quality over quantity but what I really enjoy is the depth of a post/roleplay which only really comes with quality and quantity in my opinion. Grammar, imagery and a character's personal voice should all be part of a post's style and the content should fulfill some or all of:
[list]
[*] a) advancing the plot in a relevant way
[*] b) developing your character in an appropiate way
[*] c) developing a character relationship or
[*] d) subverting/manipulating the flow of the story (in freeform/sandbox roleplays)
[/list]
People would probably call some of of my writing unnecessary fluff which they are perfectly entitled to think. I personally want to see the reasoning, the thoughts and emotions behind a character and their decisions. The writing shouldn't be about winning but that's not an easy thing to managed; subconsciously most of tend to find ourselves seeking a win, myself included. I think the best roleplays are a challenge to develop, should have intense collaboration between writers and characters and overall leaves you with a unique experience.
