It depends on the quantity of such posts. If there is only 1 important post at a time, then pinning could be used, as suggested by @soyrosa. Or if there are more important posts, but not too many - let's say 1 a day, then we can show it as our top recommendation. In case there are more than that, I think the best would be to really keep them in a special section.
