You're much more organized than I am... i write the weekly round up for my league, but its generally just whatever the heck I feel like writing about.
I have a few newbs in my league, so I try to help them out by pointing out really big obvious things like "hey, your player just got injured for the year" and stuff like that. There's also a fair amount of puns and trash talking.
Last week, I included a rant about Bill Belichick and why must he hate fantasy footballers.
After I went 0-4 this year, I announced in my newsletter than I had fired myself as coach of my team and that my cat was taking over... the team is 3-0 since I made the switch, so that's an ongoing joke.
Mostly, I just try to be funny... for the most part, its a big hit.
