Just a quick note, I honestly think that there are dozens of people on the forums whose posts could be reasonably considered "shallow and unsubstantial" - and they don't have to deal with a forum posse of at least 2-3 people chastising them day and night. I am a wordsmith by profession. I could easily hammer out 500-word posts regularly and I would actually enjoy it a great deal, though I think a lot of people would then be bored to tears. The point of online communications in this day and age is precisely that a lot of it is short and succinct. That is why Twitter became so popular despite limiting users to 140 characters (initially). The truth of the matter is that most people's attention span is considerably shorter than it used to be 20 or 25 years ago, and most writers I know are getting with the times. It doesn't mean most professional writers like myself can't hammer out long, drawn out and intricately reasoned essays. We can. The interest isn't quite there any more, for the most part. So yeah a lot of people in this day and age keep it short and sweet, because most people expect short messages. It's the nature of communication in the 21st century, whether we like it or not.
