A few days ago I introduced a filter on this usenet mailing list to eliminate all posts coming from google groups. I strongly recommend you all do the same.
It is now a very pleasant experience to read the list. True, some threads start with a troll-feeder, and sometimes I miss the start of an interesting thread where the OP is using GG. Like the poor, we will always have trolls and troll feeders, but over-quoting means that I seldom miss the gist of the very very few interesting threads started in GG.
