For example: best hotel pool in vegas. Seems simple enough. Circus Circus actually has a waterslide, but if you dive deeper (read a hundred reviews manually) you find out parts are often shut down, and the hotel itself is quite trashy and smells bad and has bad service (explains the really cheap room rate). But do you find that information on blogs? No way, they just include all the hotels with pools and copy in the verbiage directly from the hotel websites or other blogs.
There's probably an actual traveler blog out there that tells you all this and has great information, but it's hidden by all the SEO optimized trash blogs.
And this example can be applied to so many things we do all the time. Try to find a product you want on Amazon without spending half a day sorting through reviews and trash blogs.
So, personally, I think the future will be actual human service. I'd pay a few bucks to call up a service to answer these questions definitively for me.
