A pet peeve of mine is bad opening posts: I dislike seeing a poor opening post after going through the effort of making a character it's really aggravating.

Given the time it takes to write a decent post, doing anything less is unforgivable. We even have the option to edit posts once they're up, and often I'll read over what I've just posted and make minor corrections for sentence structure and clarity before letting it be.

Also little touches like artwork, use of colour and formatting can help a lot when writing in this medium. THe tools are there, we may as well make best use of them. :)
