WOF: How many email accounts do you use?

I regularly use four separate accounts. Besides the standard personal and work addresses, I have an ancient account that's dedicated to things like registrations, purchases and subscriptions, while another is solely for times when I'm not comfortable giving out the others. All of them are funneled through a single Gmail inbox, which makes it easy to keep tabs on everything.

According to recent stats (PDF) published by The Radicati Group, the number of worldwide email accounts is expected to increase from 2.9 billion in 2010 to over 3.8 billion by 2014, with around 75% belonging to consumers and 25% being corporate. Unsurprisingly, the report also suggests that the average user has about two addresses. While that's entirely plausible, we have a hunch you aren't the "average user" – right?

What about you? How many accounts are you actively using and do you prefer checking them through a Web interface or a desktop client like Outlook? There's a poll eagerly awaiting your mouse click after the break, but don't be afraid to leave a comment, too.
