I don't think you are out of line, but I think your last sentence really gives a good reason for Rusty to keep initiating new topics.
I haven't personally felt he is pushing any particular agenda. Usually the post simply is the same item he has written for the newspaper. As I review his postings I see that many of them are simply informative and ask what we think. Many get no replies, so I guess we don't have any opinion, whereas others get a great deal of activity.
Just my opinion, but I hope he keeps posting new topics and asking what we think.
One other aspect that is important to me personally. When I go North to become Summerguy I do not get the local papers. Using this forum and the online news keeps me informed about what is going on down here at the local level.
I'm about done posting on this site. It seems it's become over run with the editor's posts. I'm sure he thinks that he's stimulating discussion, but at the same time he's pushing his own agenda. He should put more of his ideas and material in the newspaper and not re-post it here.
I hope I'm not out of line because we have had some lively topics bantered about in here.
