Why would anyone use hotwire.com?!

I've been searching all the various meta-travel sites in order to find the cheapest way to get Molly to Cincinnati for Dave's wedding. I was finding pretty much the same flights on all the sites, but Hotwire added an extra layer of stupidity into the mix.
Take a look at the screenshot:

$249 is the same amount that I was finding on most other sites, but only Hotwire refused to tell me when the flight takes off, when it lands, what airline it is, and all that other information that is, I don't know, essential?! Maybe I'm being too harsh on Hotwire though. I mean, they do give you "helpful tips." They are nice enough to tell you that the flight will depart somewhere between 6am and 10pm. Wow, a 16 hour window? That's so generous. Hotwire is even worse than Time Warner's policy of, "We'll be there between 9am and 5pm, so just sit around and wait for us."
