Evernote Secures $20m in Funding

I think this is awesome! These guys produce a service that has traction, has a loyal following, and AFAIK has never had an issue. I use it, love it, and recommend it. The greatest thing about it is how they have it on all your devices (almost) and I find myself branching out into their "life memory" strategy by, for example, creating a recording of my 15 month old son laughing. That's on top of the business productivity applications I use it for.

My question, though, is this:

Evernote has traction. Evernote is growing. Evernote has subscribers. Evernote has partners developing plugins for it (Evernote Trunk)

What do they need $20m in funding for?

Is it that word of mouth adoption only goes so far? Is it to speed up adoption by buying installs on new computers?

What would you do with $20m if you were Evernote?
