NEW YORK (

TheStreet

) -- Speaking for the first time publicly since the IPO,

Facebook

(FB) - Get Report

CEO Mark Zuckerberg addressed a slew of issues at

Tech Crunch Disrupt

, including the freefall in the share price, the opportunity in mobile and search, Zynga's woes, and whether the company would build its own phone.

Hosted by

TechCrunch

co-founder Mike Arrington, Zuckerberg was in front of over 3,000 people as investors, developers, media and others wanted to know about the long-term viability of the company.

The Facebook co-founder and CEO first addressed concerns about the 50% decline in shares since the

IPO in May

. "Obviously the performance of the stock has been disappointing," Zuckerberg said.

He spoke at length about mobile, which is how Zuckerberg wants the company to be viewed over the long-haul, given the tremendous growth the company is seeing in its mobile users. Here's a recap of Zuckerberg's highly-anticipated interview:

Zuckerberg went on to talk about the importance of making money, even as he defined Facebook as a mission-driven company.

Arrington asked him about how the negative share price performance is affecting morale at the company, and the compensation policy at the company as a result.

Zuckerberg noted that he thinks it's a good time for people to join, stay, and "double-down on the company."

When asked about mobile, Zuckerberg became noticeably excited, talking about the company's future on mobile and how it can generate revenue through advertising.

Zuckerberg touched on the mistakes the company has made when it comes to mobile, and he noted that building the app in HTML5 was the company's biggest mistake.

He noted that the work done since abandoning HTML5 for native (apps as we know them) is so much cleaner and faster, especially the iOS app for

Apple

(AAPL) - Get Report

, as well as the app Facebook has for

Google's

(GOOG) - Get Report

Android.

.

Arrington asked Zuckerberg if he coded anymore given that he's the CEO of a multi-billion corporation, and noted that he still "codes for fun on the side, but out of respect for other folks, I don't code for the main branch anymore." He also said, "Everything I do breaks, but we fix it quickly."

The

Instagram

acquisition

was brought up, and why the Facebook did it when they already had their own mobile camera app.

The subject of a Facebook phone was brought up, which has been rumored about for months. Zuckerberg was quick to shoot it down, saying it didn't really make sense for the company.

He mentioned all the companies that are building hardware (it's unclear whether he meant phone or tablet, though they were talking about phones) and mentioned Apple, Google,

Samsung

and

Amazon

(AMZN) - Get Report

as hardware companies.

He touched on the relationship with one hardware maker, Apple, which Facebook already has a strong relationship with. He noted that eight out of the top ten iOS apps are already integrated with Facebook, and the company can go really deep with its iOS integration, as well as Android. Apple announced Facebook integration into iOS 6, its next mobile operating system at its

developer conference

in June.

Touching more on mobile, he noted a particular interesting fact about how he spends his time.

Moving away from mobile, Arrington asked about Google+ and whether that "pissed him off." Zuckerberg shied away from that, but did talk about search, which he thinks is an "interesting opportunity" for them.

The conversation then moved away from search to the desktop platform, notably its partner

Zynga

(ZNGA) - Get Report

. "Zynga's had a rough few quarters," Zuckerberg said, before noting that they're "fundamentally a strong company, but they've lost some share on our platform."

He said that the Facebook platform shouldn't be about building apps inside the platform, but the real value is when information is brought back to the apps. "

Spotify

is killing it.

Airbnb

is doing a lot of interesting stuff. Nike+ is doing interesting stuff.

RunKeeper

," were cited as examples of apps that are benefiting from information outside Facebook's social graph.

The conversation wrapped up with Arrington asking Zuckerberg if he was still having fun and whether Facebook was being underestimated. He noted he was having fun, but it's more about the mission than having fun.

Facebook shares jumped on the back of Zuckerberg's comments, gaining 3.5% in after-hours to $20.11 in heavy trading.
