Thing 5- I absolutely love Flickr. I don't have a personal account, but many of my friends and family do and they're constantly posting pictures. Here is a link to one of my favorites from some friends who visited Washington D.C. this summer: http://www.flickr.com/photos/mitchviren/3652281499/in/set-72157620195812583/. I was able to visit D.C. in August and got to see the Library of Congress!!
Thing 6- I also really like the mashup site Montager which allows you to create photo mosaics. What a cool idea.
Thing 7- This is an interesting tech article that I found recently about Google Wave which will be released in 2010. They call it a web application which aims to replace email. http://www.cnn.com/2009/TECH/09/29/google.wave.beta/index.html
