Unfortunately the system will come up with old sticky posts also. Imho it is of better use, if we get real the posts with the last changes in the overview - like it is described in the header line.
That's not a solution. That's a - not wanted - workaround.
As mentioned, I want to keep pinned topics pinned. There are good reasons to have pinned topics. But there is no good reason to list them on top in that kind of "latest" topics.
