Blame the Web for accelerating the spread of gossip, inciting rude behavior, and distributing more photos of Paris Hilton than anyone needs in a lifetime. At least it's helping humanity learn how to flirt.

The coy side of the Internet emerges every Thursday and Friday when searches on flirting swell with anticipation. The weekend's nearly here—and love awaits! Both genders hit the Search box for assistance, regularly boosting buzz on "how to flirt with a guy" and "how to flirt with girls." Note that one side looks for "a guy" while the other seeks "girls" in the plural. Men are such rats.

Meanwhile, the e-methods of coming on cute and witty keep gaining in prominence. Demand for flirtatious comments, MySpace layouts, and text messages has never been hotter. One hint: "i wanna txt u up" doesn't fall under "flirty text messages" or "cute flirty quotes." It's just rude.
