I find this so frustrating. I read many technical articles in a day, none really that significant. Then a day or two later I realize something in that article is now relevant.
I use the search history feature in IE. For instance I know the article was about SQL Indexes, but that piece of garbage doesn't allow to search and sort by date. Considering I might view thousands of articles about SQL Indexes a year...You can see why searching by keyword isn't helpful if I can't sort by date. What I really want is a way to view pages by order visited and search.
