Today we’re launching Facebook on Quizlet. This feature lets you use your Facebook account instead of a Quizlet account to log in to Quizlet. This removes the need to create a Quizlet account with a password and email address and birth day–you just use your Facebook!

If you already have a Quizlet account, you can use both. If you do authorize Facebook with an existing Quizlet account, Facebook features on the site will only show when you are also logged into Facebook (there will be helpful prompts that show you how to do this).

In addition to logging in with Facebook, you can do some special Facebook things within the site:

When you post a new set (that’s not private), you have the option to post a link to it on your Facebook page, so that your friends on Facebook can see what you’re studying:

You can also see your currently online Facebook friends that are also studying on Quizlet. The My Groups page becomes My Friends and you’ll see something like this:

If you’ve added Facebook to your Quizlet account and want to remove it, you can do that in your preferences page (link at the top-right corner).

This is just the first start on the Facebook project — giving you the basic features developers Facebook gives you to integrate websites. As we hear suggestions and explore the platform more, we’ll add things that make this integration even more useful.

So, what do you guys think? Let us know

P.S. I also slowed down Space Race a little and made some bug fixes. Post a comment if you see something amiss. Thanks!

Want to advertise your website or service on Quizlet? Now you can, through Google’s AdWords advertising program.

You can even target Quizlet users in a specific geographic area, or only those who use Quizlet to study a specific subject (e.g. Spanish). And there’s no minimum budget for advertising on Quizlet – you can spend as much or as little as you find effective for your business.

Here’s how to get started:

1) If you don’t already have one, create a Google Adwords account here: https://adwords.google.com/

2) You’ll be prompted by Google to set up your first ad campaign, which you might want to call “Quizlet Campaign”. It may take a few minutes to get set up and familiarize yourself with the Adwords system, but it’s worth it!

3) One you’ve set up your campaign, go in and change the settings, so that instead of showing your ads on Google Search and Search Partners, they only show on “The Content Network,” and specifically on “Relevant pages only on the placements I target.” Once you’ve changed these settings, within each ad group you create (for example ‘Quizlet French Pages’), you will see a Placements tab. Click “Find and Add Placements” at the bottom, and then type Quizlet.com into the ‘List URLs’ box. You’ll then see a list of the ad placements that Quizlet offers. Select the ones you want to try.

4) Note that Quizlet accepts text ads – the standard Google ads, and also the more distinctive image ads, so long as they are 200 by 200 pixels. These will get you the most visibility on Quizlet. We also offer you a choice of advertising only on specific areas of the Quizlet site (e.g. by study subject or by ad position). And if you want to reach students in a specific geographic area, you can target that way as well.

5) If you’re just getting started with Google Adwords, you may want to visit Google’s Adwords learning center (http://www.google.com/adwords/learningcenter/) and watch a few of the videos, which show how simple advertising this way can be. Once you’ve set up your ads, they’ll start running on Quizlet immediately. Good luck, and let us know if you encounter any problems.

Hey all–

We’ve made a ton of progress so far on our big January push. We’re finishing up the last touches on Facebook Connect, the iPhone app is coming along well, and one of our super secret projects is on track to make a big splash.

In order to communicate quickly, I’ve decided to get a Quizlet twitter account. Is Quizlet down? Having issues? There’s a good chance you’ll find some quick info on Twitter. I’ve been skeptical of Twitter for awhile, but with all the chatter about it these days (see this awesome super bowl visualization, I figured I’d give it a try.

That’s all for now, just wanted to keep everyone in the loop. Expect some big things in the next couple weeks
