If you care about what I put online, I recommend you try to find me at these services:
Facebook: Things that I want friends and family to see will go on Facebook.
Google+: I use an Android phone so this is convenient for me to store personal information. I upload my entire photo albums with Picasa. I "check-in" to keep track of how often I make it to the gym, and where I go with the hiking club. I use +1's instead of bookmarks. Search for me here if you want inconsequential information about my life.
