It was a big year for LinkedIn.

While it seems like the stock of newly public tech companies such as Groupon, Zynga, and Facebook have been stagnant or falling, LinkedIn's stock has been on a tear.

Add that to the slew of new user-facing features on LinkedIn's website and apps, and you can see why things are looking pretty rosy for the company overall.

Here's a quick recap of the biggest changes this year:

We had a quick chat this recently with Deep Nishar, LinkedIn's senior vice president of product, to go over what 2012 was like for LinkedIn and what we can look forward to in 2013.

Below is an edited transcript of our Q&A session with Nishar:

Business Insider: Last we heard, LinkedIn saw huge growth in mobile traffic. Where are you at now?

Deep Nishar: At the end of last quarter about 25% of our weekly active users coming from mobile. That's doubled in about a year's time.

BI: Do you attribute that to the new apps for iPad, Windows Phone, etc.?

DN: Overall, there's obviously a shift toward mobile, so we shouldn't forget that. But toward the end of last year we launched our new iOS app and that has gotten a lot of traffic and accolades. In March of this year we launched our iPad app, which has also done very well. We also launched a Windows 7 app and are working on a BlackBerry 10 app.

When you combine the entire portfolio there's a lot happening there. In terms of growth, we're seeing good distribution between both the mobile web and apps. The apps are clearly taking a predominant share of it, but on things like the iPad, people clearly use the mobile web browsers too.

BI: As far as alternative platforms, are you looking into Windows 8 and Android tablets?

DN: We're looking at how things perform in the market before we get to it. Mobile is an ever-changing cycle. We want to make sure that as new operating systems come out, we continue to keep the apps very current on those operating systems. We are definitely very focused on existing apps that are out there and making sure they're very current when the operating systems get upgraded by the various manufacturers.

BI: What about Android tablets like the Nexus 7? Why isn't the Android version of LinkedIn optimized for the bigger screens?
