Well I believe that there are several problems...

1) It's obvious that writing an aar can be a great time sink - the more thought you put into it the greater the time loss - and some people just don't have the time - or decide to put their time to better use fast enough - you'd be amazed for one how much time I wasted simply agonizing over the exact nature of my last update in my aar - someone with a head on his shoulders would think me rather insane to begin with.

2) The community here is not really into aars. Compared to let's say the community over at the paradox forums (the EU games etc).

3) As a direct followup to 2) there is little "support'' given to those who actually try to write an aar. I've observed this many times, and it's sometimes the case that an aar writer feeds off the interest of his readers [granted there are a few who don't care if they have readers at all - but they are the exception not the rule]. So then when the aar writer thinks there's not enough interest, he'll also lose interest in writing. Nothing like posting an update you spent a lot of time working on to be met with complete virtual silence. You can then shift to 1) and question the reasons for spending this much time on your aar - after all you can fantasize on your own, no need to format your fantasies on a website.

Anyway, those thoughts will suffice for now... dinner beckons... yuum...yuuum.
