This is advice specific to here, but I think that's what you asked for. Plus, it'll help you get better at writing characters in general.

In every post, think about what your character's physical, mental and emotional reaction is to what happened in the posts your replying to. Then write what they think about this, either by showing it through body language or facial expression, or just telling it through a straight-up inner monologue. Then, after that, you write about what your character does and says in response to that.




For larger works, yes, redrafting is important, but I disagree that you usually have to burn everything to the ground. I never do. Then again, I've never been published so maybe that's better advice, but I'll tell you that there is often something of value in the first thing that comes out of your hands. 

Basically, write with absolutely no regard for the quality or even basic spelling and grammar of your work. The goal is simply to get a first draft [b]finished.[/b] (This can often be the hard part.) Then leave it and come back the next day and fix all the issues that are easily fixed, like spelling, grammar and glaringly bad prose. Then take several days off and come back to it with the mindset of a critic, but DON'T act like the whole thing's worthless. Go through it systematically, note how every paragraph could be improved or changed for the better, how plotholes could be resolved and pacing could be tightened up or fleshed out as appropriate, and make these changes. Do this a few times, a few days apart, and again at the end of the book when you've figured out the aim and theme of the whole book. You'll probably have to change a LOT of the beginning to fit these aims and themes.
