@roger,
I mostly agree with you and farmerman..
but back in the days I used to post land use articles, or, usually, links to them (watch out, I'm going to do that again though perhaps differently), two things were going on.
First of all, to post the articles I had read perhaps twenty or thirty or forty others myself and selected what I though might be interesting. Thus I was sort of tired as I made the post, re making some sort of smart sounding starter comment. And secondly, I didn't want to bias anyone with some mini rant by myself - I was hoping to hear comments and then contribute to the discussion.
This worked some fair part of the time, and sometimes not, when the interest wasn't there.
Mostly I already read or don't read the sites from which people do clips. But not always - so I am occasionally interested in a new source.
I am more aggravated by folks who don't give the source, very annoying.
edit to say, I often gave at least a mild personal comment, but sometimes I didn't. Never meant that as some kind of near spam.
