Welcome to WebmasterWorld Dj_JMJ
I think you've been reading some of my posts from years ago!
I've just taken an in-depth look at all the sites in my niche. Everyone has been completely destroyed this year.
To be very polite, G's SERPs are almost a total horlicks ... Honestly my global industry has given up with G, only two major trade portals remain open, mine and one other, and even mine is only there because I'm an awkward ****
Has anything replaced these widget trade sites in the realworld? No, no, no, no ... far from it, the realworld stockists are doing better than ever, securing more business simply because G does not have the answers about those sites.
G does not have the answers because realworld traders in my industry are not giving G the information, they are not giving G the information because they do not want it to be BROADCAST to all their competitors via The Net and end up driving their prices and profit margins down!
Your industry will defintely vary since this is for my widget industry however I'd bet that other industries are seriously looking at doing similar things.
