How to Live Your Entire Life on Facebook

We'll concede that the average Facebook user is doing nothing productive with their day, likely burning hours on end playing Mob Wars or agonizing over the finer points of a 25 More Things You Didn't Know About Me note. Or perhaps goading colleagues into frittering away their time in endless rounds of Scrabble. But it turns out that the uber-popular social networking site is good for more than just fooling around. In fact, many Facebook applications can be so surprisingly productive and useful that you might not ever have to leave its environs during your Web-browsing day. Dare we even suggest you might be able to get honest-to-God work done using Facebook? Poke your boss and make sure he knows! Here are some of our favorite Facebook apps for the truly obsessive:

This is about as close as you can get to doing actual work using Facebook. Zoho has ported a hefty chunk of its popular Web-based Zoho Online Office application suite to work within the Facebook site. When you sign up, your Facebook account can be linked with an existing Zoho log-in (or you can set one up on the fly), and you'll find all your saved and shared documents available for browsing -- and for sharing with other Facebook+Zoho users. Unlike the other apps on this list, editing documents ultimately opens a new window on the Zoho site, rather than being hosted within the Facebook app directly; but rest assured, you can hustle back to your safe zone once your work is done.

Just because you're a shut-in who never logs off of Facebook doesn't mean you don't need to eat once in a while. The TripAdvisor-developed Local Picks app has more than 530,000 restaurants covered in its entirely Facebookized recommendation utility, letting you read millions of reviews and, of course, add your own. An easy map-and-zoom system lets you locate the nosh nearest your intersection. You can also compare your ratings with those of friends -- and find out who among your Facebook circle has the same "dining compatibility" as you. Don't forget to chew thoroughly.

Nothing else quite goes with the Facebook experience as drinking copious amounts of wine. And true to form, several Facebook applications are designed to appeal to your inner wino. Bottlenotes is largely self-explanatory: It's an application that lets you archive personal tasting notes and opinions regarding everything you drink. Just type in the name of the wine, some comments, and a star rating, and Bottlenotes archives the memo for posterity. Naturally, you can compare notes with friends and also add "wish list" wines that you'd like to buy (or receive as a gift -- hint, hint).

What's going on out there in the real world? So-called "meetups" are becoming an increasingly popular way for like-minded citizens to get together and expound on their love for beer, board games, Obama or just about anything else. Mind you, attending a meetup does require leaving your house, so if that's too much trouble, you can get a lot of enjoyment out of just browsing the application to see exactly how far out some of these meetups can get. Turns out people will meet in real life to talk about anything.
