Let's get right to the point - Twitter is only as useful as you make it. Since 2006, Twitter has grown from a cultural phenomenon to an infinitely useful social media marketing tool. Regardless, the web application known for publishing users' messages in 140 characters or less, is probably not first to mind when your goal is productivity.

But maybe it should be?

It may have taken a while, but Twitter clients around the world are developing a growing number of useful applications aimed at improving your day-to-day functionality. Because you can access and post to it from nearly any device, Twitter is a surprisingly ideal and efficient way to set reminders, update Google Docs, write to-do lists, etc.  Assuming you already have a Twitter account, included in the Fission Social Media package, we've compiled a list of some of the top (and did we mention free?) Twitter-based applications that aim to help organize and streamline your day-to-day life.

1. Toodledo and Remember the Milk: Both of these tools allow the user to set task reminders and track them through completion, as well as sync with your existing iCal (or other calendar) software. Toodledo also offers collaboration options, ideal for sharing task lists between co-workers and family members.

2. Twitter Timer: Need to remember something? Send the Twitter Timer a direct message and it will tweet you back at the designated time. For example, 'd timer 45 call mom' reminds you in 45 minutes.

3. Evernote: An "infinitely useful" note taking (and organizing) service. Send yourself notes, reminders, and to do's via Twitter and access them later through your computer or phone. Use in conjunction with your other devices to store and access saved tweets, photos, screen shots, and anything else you can possibly imagine.

4. Xpenser: Track expenses instantly by tweeting to your account. Xpenser can also be used to track mileage, convert currency, and import bank and credit card statements. Access your account through Twitter, Email, SMS, or Phone.

5. Twittercal: A simple solution for users who don't want all of the bells and whistles of other calendar applications. Twittercal connects your Twitter account to your Google Calendar in a few easy steps.

6. Twilert: See who's tweeting about you and what they're saying with Twilert. This application enables you to receive email reports of any tweets containing your brand, product, service, or any other keyword that you specify. An extremely useful tool for any growing business.

We know it's been said before, but it's becoming quite evident that Twitter is not just for the birds.
