GetLoudPC was new yesterday. The rest have been around for a while.
I have a good straegy to doing Blink. I visit the sites in roughly point order. Smartpages first for 120, then Furniture Fan (1) and (2) for 80 each, then on to HealthScout for 60 and so on. Then I pick up all the 5 pointers. That way if I get distracted, I got the biggies first. Then, when I go in the next day, I just go to "My Recent Visits" off the home page and there are all the links for the Blink clicks I took the last time I did Blink! I take the "More Sites" link off the home page under the Recent Visits list so I can see them all.
Once I click on all the links I took the last time, then I go to "Fast Clicks" to see if there is anything new . If there is, it will show up at the top of my "Recent Visits" list the next time and I work the point value into the right place in the list. So, I did GetLoudPC for 25 points right after Overstock.com.
