Twitter is not a profitable company. Maybe it's on its way to becoming one, or will be someday, but the company's most current numbers show it taking a loss. But as the New York Times makes clear, plenty of myopic, gung-ho investors are trading Twitter like it's Exxon.

The Information just proved that it's worth the $400 price of admission. On display in an interview with Y Combinator cofounder Paul Graham is the clearest picture of Silicon Valley's unacknowledged sexism to ever find its way in print.

In July, Tumblr's tween creator David Karp predicted native, multimedia advertising would be the most exciting, dazzling part of the company. At the year's end, they're running depressing link ads for the yellow pages.

Earlier this month Andreessen Horowitz hired the secessionist, Balaji Srinivasan. The academic and entrepreneur infamous for suggesting that techies build their own society "outside the U.S." scratches off the secessionist label with one hand, even as he writes dreamy odes to "a cloud country of our own" for Wired. Now, Srinivasan is aiming his science fictional phasers at death.

The overwhelming evidence against giving a 20-something Stanford kid millions of dollars for a startup and letting him run wild continues to pile: an anonymous post by a former employee says Clinkle's CEO screwed his staff out of money.

Karaoke is fun because it's a group activity, usually involving a lot of beer and yelling loudly with your arms around others. Using your smartphone is the opposite of this, and yet, here is Just Sing It, a bad app with a celeb endorsement. In a rare victory for common sense, Just Sing It is already tanking.

It wasn't just Christmas, kiddos: Google's swift and merciless de-listing of Rap Genius has sent the site's traffic even further towards oblivion, as shown by the newest numbers out of Quantcast.

"We effed up," lyrics annotation supersite Rap Genius admitted this week after its SEO cheating was revealed. They sure did. And there's good reason to believe this isn't just a gaffe for the cartoonish startup posse: a Google eff up could haunt them forever—but no one search should have all that power.

On Christmas Eve, Gibson Security published information on how to exploit loopholes in Snapchat's security that "allow mass matching of phone numbers with names and mass creation of bogus accounts," reports ZDNet. Gibson published the codes because they were "sick of" Snapchat ignoring their warning since August.

It's been a banner year for Silicon Valley's blog of record—investor cash is flowing, and incomprehensible gibberish companies are flourishing. As are incomprehensible gibberish articles about them.

Quantcast shows that the number of unique visitors to Rap Genius has dropped 60 percent since Google punished the startup for its questionable SEO scheme. Last year, unique visitors to Rap Genius only dropped about 15 percent from Christmas Eve to Christmas. Rap Genius has not responded to request for comment from Valleywag sent yesterday and today.

The cofounders of Rap Genius got lumps of coal in their Christmas stockings, courtesy of Google. Matt Cutts, Google's head of search, promised he was looking into the lyric site's SEO scheme. His punishment this morning was swift and brutal.

There's nothing wrong with having contempt for your customers—maybe your customers really are stupid. But if you're the CEO of a prominent company in the midst of popular backlash, hoping to IPO someday, don't make your contempt obvious on Twitter.

How has Rap Genius distinguished itself from all the other lyrics sites? With sweet, sweet old school spam techniques, or as Silicon Valley likes to call it "growth hacking." The tactic is so shady that Matt Cutts, Google's head of search spam, felt compelled to publicly state that his team is "aware and looking into it."

The 2016 presidential race already has its Mama Grizzly. Meet the Ubertarian: "They support government regulation—except when it inconveniences them."

Since Yahoo! decided to buy itself many million cool, popular teens, we've been wondering just how much the billion dollar purchase is working out. Are they clicking ads? And more importantly, just how popular did Tumblr make its historically square parent company? It was murky before, and now they're making it even more opaque.

Although we try to focus on the positive, innovative—and dare we say revolutionary?—moments in tech here at Valleywag, the startup world isn't without its occasional bad eggs. It's a shame this crowd had to tarnish an otherwise lovely community—here are the worst bad actors of an otherwise golden year.

Jack Dorsey is now on the board of Disney.

If there's anything Silicon Valley enjoys more than money, it's jargon: Buffer, a company that sells an "efficient solution to handle sharing on social media," just published its internal formula for who gets how much money. All in the name of "radical transparency." But is this a "good idea"?

Tech corporations perks are finally growing up. AllThingsD's Jason Del Rey reports that Google has spoken with Lending Club about the possibility of using its cash holdings to offer low-interest loans to Google employees.
