Then don't read them. Complaining about what other people write is the height of vanity.
I don't see how a top 10 traffic site could possibly be overlooked by marketers. If it were a value, they'd shift there until it was not, and that isn't happening at all. The data shows that you are incorrect.
I didn't read it, just briefly skimmed, my comment is related to seeing the reoccurring fb rants on YC.News.
In case you've missed it there is a lot of advertising happening on fb, some major brands include Blockbuster/BMW/Virgin America.
Where I see the value on fb is search ads for smaller advertisers, the cost-per-click on some prominent keywords are so much less than google, if the fb demo is your target, this can be a very cost effective channel for reaching them, plus this is where they are spending time.
My Opinion is that facebook is one of the best valued ad networks for advertisers right now and the flood of brands is a matter of when not if.
