here is my response for :
4. COMPOSE a blog post (title it ACTIVITY 5) that includes your reflections on social bookmarking.
I'm not really interested in this one. I don't keep bookmarks for 2 reasons. #1 website addresses are always changing and it is easier to find things by searching on google for sites that i don't go to on a daily basis. #2, i use RSS feeds from all of the websites that i do visit everyday. this sends all of the headlines to me, instead of having to go to a bunch of websites, i just click on button and get all of the info, its a lot quicker.
