3 must use web apps by @brandoncorbin

• Dropbox http://getdropbox.com – I use DropBox more than any other application – without really using it. Dropbox is like one of those little thumb drive, but online. 2 GB of space for free. You install the app on any computer you have, and boom there are your files. Just signup, believe me, you’ll never look back.
  

• Aardvar http://vark.com – Aardvark is a community of people who answer (and ask) questions. I use it via my instant messenger to get advice on anything from cooking to coding – from other real people.
  

• Delicious http://delicious.com/popular The coolest and most recent happenings online (thanks to human ranked and submitted sites). If you need to know what’s going on Delicious should be your first step, even before Google.
