Unless the trip reports are on a blog I do not read already, I do not read it. I have no particular problem with people doing it—I just won't read it. Same with video reports. I won't watch them, but that is my choice.
As for the content, some sense that a journey is taking place is enough. I enjoy ones that focus purely on the transportation the most, but I do also subscribe to some that are more focused on the location.
In the end, I guess I am saying the status quo is working fine, if only there was encouragement for people to post trip reports here over their own blog.
