IFTTT (which stands for If This Then That) is a great tool to automate many of the things that you may already do online.  The web service uses “recipes” to create “triggers” that will act when certain events happen.  For instance, my favorite so far, you can create a spreadsheet that will contain every tweet that you favorite on Twitter.  This becomes really useful when you are at conferences and do not have time to keep up with all of the tweets that you like.  You can favorite them, have them automatically added into the spreadsheet, and go over them later when you do have time.  This can also be very useful for saving resources or keeping you up to date on your “to do” list.
