Time. That has a lot to do with it. Many here will tell you that they just don't have the time to keep track of everything.
Paradox isn't just PR, but also on the tool development team too.
There is no one person here who's job it is to just collect information (either news worthy or not) to have on hand (now over at the Maintainers we'd have a line of people willing to do that job).
Lynnutte may have to do some "Investigative Reporting" in that read through the forum, try to find things that might be of news worthy to mention and report.
That takes time too!

So asking questions can help also. Like:
"What new Ages have been released? Where can I find info on them?"
"What new projects are the GoW working on? Which ones are completed?"
Things like that of course.
