I have had some success adding "forum", when looking for trade discussions; eg: controls & automotive. With all the walled silos on the net, this is much less useful with every passing day. On the bright side, I don't have to use -twitter & -facebook, so there's that.
This is great but it seems reddit has done something to mess with their date reporting. When looking for recent posts, I might see a result on Google that says it was posted in the last few days, but on clicking the result will actually be from years ago.
might also be google. I've noticed inaccurate dates that don't appear anywhere for some of my pages. my only theory as to why these were displayed is that google interpreted a (server side) randomly generated number in an inline script as a timestamp (but i can't know for sure that's what happened)
Not sure for how much longer this is going to work. Plenty of marketers make fake posts there in grassroots campaigns. Reddit itself is an advertising company.
