Agreed on this. I think the quality of Google searches has gone down dramatically for this type of search, because forum posts are often where people have questions answered. It's not just product research; programming, homework questions, general subject matter, all are often answered best in forum posts.
Could be. I'm not really sure if the quality of search went down, it seems to be a lot better imo after Panda+Penguin purged a lot of ridiculously spammy pages; but I still want a way to just search discussions.
