However, as an indication, I have just put together a blog post detailing the weekly progress reports for weeks 2 to 5 (Available here), and here are some interesting facts you may find relevant to your query:

On the first five weeks from when I started this experiment in 2008 I received a total amount of 198 emails. Take into account around 3 minutes to handle each of those emails (And that could perhaps include handling spam, archiving of emails, more or less complex emails) and it will tell you the time I saved in processing those.

Then in the first five weeks of 2009′s experiment take into account I have received 106. Do the same math of 3 minutes per email and you will see how I have spent half the time, from that time!, processing email, coming nowadays to an average of 13 to 15 minutes a day processing email.

Hope that helps you get some idea of the kind of “time savings” I have gone through, but, like I said, these time savings are more along the lines of reinvested time into collaborating within my communities / teams / networks spaces.

Thanks again for the feedback comments. Greatly appreciated!

Stay tuned because of the next few weeks I will be sharing some social software tools tips for those I use the most on a regular basis and you would be able to see the context in which I use them as well as describing their usage itself. Thanks again for the commentary!

Apart from the qualitative advantages of using other forms of communication than email, what are the quantitative advantages?

Have you been able to measure specific time savings by not using emails. e.g savings by not having to deal with spam etc, savings in time because other forms of communication take less time on average.

What I would like to understand is what is the nett time saving (measured in person hours or days) over the entire year by not using emails.
