We’ve reached the final installments of our year-end special looking at this year’s 20 most-useful social media tools. If you missed out on parts one and two—which counted down Nos. 20 through 1—you can read them here and here.

In a few days, we’ll unveil the five most-useful social media tools of 2011, but first, Nos. 10 through 6:

10. The PRINT social media performance analysis service from Sociagility. While this was only launched a month or so ago, its potential in helping brands and organizations make insight-led decisions about social media strategy is plain to see. Your PRINT score is a combination of your social media channel and attribute performance, and is based on data measured against your pre-defined competitor set.

9. SocialBakers.com. This analytics tool features every imaginable social media statistic you’ll need and is especially robust when it comes to geographic and demographic breakdowns for Facebook. Superb stuff.

8. Zooshia.com. One of the more quiet tools of 2011, Zooshia enables you to create your own widgets for blogs and websites. You can create a “Zoosh” of your Facebook or Twitter feeds or from a combination of sources. Best of all, embedding the code after you’ve tailored your widget is incredibly easy.

7. Pokki.com. Pokki helps you create Web apps for your desktop, giving you easy access to your favorite sites without having to open up a Web browser. The Gmail desktop app is especially sweet.

6. Contax.io. You may have stumbled across MyTweeple in the past (a Twitter-specific contact management system), but in 2011 it evolved into Contax.io and added Facebook functionality, giving you a central place to manage your fans and followers. It really is a beautiful thing.

The finale is coming soon. What do you think will end up in the number one spot?
