I think that people generally should strive to say only what they need to. Brevity contributes greatly to clarity and the likelihood of a given user to read the post at all. I'm sure just about everyone has room to improve on in this respect. I agree that there are people who especially should probably shorten their posts because I think some people use theatrics and subsequently lengthen their posts. Some people go crazy with formatting. I actually agree with ginganinja in that I was intimidated by the posts for a while at first.
That said, like Deck Knight said, post length is not dependent on integration into the community. Making a good post - which includes regulating post length - is a learned skill that people have to develop over time. It's also not a problem that's limited to this forum. I used to read suspect threads in their entirety and there were definitely some stupidly long posts in them. It's just that people forget about those because people typically don't read threads like that in their entirety.
That is not to say that concerns like ginganinja's aren't valid (I just said I used to share them), nor does it mean we can't do our part to improve the general posting quality of the CAP forum. However, this is part of the general advice to be a good poster, which is limited neither to veterans nor to CAP contributors. Even now on IRC you talk about how ginganinja's post "holds the most weight"... which could be true in a way for optics reasons, but considering your dismissive attitude lately (a context that gets lost when only looking at the responses to this thread), it seems more like you're only paying more attention to ginganinja because he seems to agree with you. Can we please talk about policy and culture without throwing out blame like some kind of lynching mob?
<+Pwnemon> ugh i think that my post got ignored because i didn't format it pretty
Like, there is such a thing as too cynical...
