A sample size of 400 is actually a pretty good sample. Assuming a global developer population of 10,000,000, a sample size of 400 would give you a margin of error of 5%.
With a population of the same size, in order to get a margin of error of 20%, you'd need a sample size of 25. If the North American developer population is even a third of this, you'd get around 5% margin of error as well, so I'd say that statistically speaking that 400 is a pretty good sample size.
I also have email archives that stretch back to the early-1990s. I pretty much still have every email I've ever sent or received.
When upgrading email clients, I often migrate my archives with me, converting them using whatever client's built-in importing and exporting functions I have available. I went from Eudora to Outlook Express to Thunderbird to Mac Mail. I also have programs that "pop" webmail off their sites (gmail, hotmail and yahoo) to consolidate them in whatever current mail client I'm using.
I just keep them in neat folders ("Old Eudora Mail," "Old Yahoo Mail")..

I think Cake would be the most logical combination of their names. Cake.
