Hear that chirping? It's the sound of $80 million going to Twitter.
Venture capital firm Andreessen Horowitz just made the whopping investment into the short-form social media site, according to All Things Digital.
Andreessen Horowitz made the investment through secondary markets, meaning they bought shares off employees and early stockholders who can sell their privately held shares to outsiders. Going in through the secondary market lets venture firms avoid the hassle of running a financing round.
