This is exactly it. The purpose of web forums is communication that you want to reach people right now (if you don't already have a well established platform). Most of it is information that, if it has any value at all (I think it does, but wanted to preempt snarky comments) it has the most value right now, and it diminishes rapidly as time passes. So having it be read by people right now is much higher priority than preservation for the future.
