What I mean is, reserved posts are not really useful for updates. Like you said above, people mostly read new posts; new comers to the topic read (skim & scan) #1 also to get the topic idea. Then updates in #2 are more likely to be overlooked. Take this topic as an example, its author changed the important contents (duration, reawarding pool, rules, stakes...) in #1 instead of updating them in #2. Clearly skimming and scanning #1 is enough to get the latest information. But in case the OPs want to maintain #1's content then a new #1 for updates is perfect (like this topic suggests).
