I would argue that compete.com stats for something like dropbox are pretty inaccurate. However, that being said, the website traffic is probably much less than the actual growth. I've been to the dropbox site only a handful of times, but I use it every day with the file system integration.

I'd love to see a graph of their bandwidth and storage growth. I'll bet that would be a site to behold.

It's a great idea, and congrats to all involved!
