By 2013, experts estimate that e-mail users will send 507 billion messages every day. Currently, the average person receives about 419 e-mails per day, with a little less than half of them related to work.
When you add up the time it takes to read and manage all that e-mail, plus time spent instant messaging, reading and writing blogs, and viewing and creating Web content, it's clear that digital communication is one of the primary uses for technology.
The open source community has created a wide range of applications designed to help people participate in and manage all that communication. A little more than a year ago, we put together a list of good open source communications software that can replace proprietary solutions. This year, we've updated that list with new information and new projects that can help you communicate with your colleagues, customers, friends and family.
As always, if you know of additional open source projects that you think should be added to our list, feel free to note them in the comments section below.
