Lifehacker, one of the best blogs in the world and an everyday read of mine, posted its Top 10 Computer Applications of 2005.
Their list and mine share Flickr and Del.icio.us.
The only app they listed that I affirmatively would not list is Yahoo! Widgets. I used that app back when it was Konfabulator and didn’t find much to get excited about. Otherwise, they list a bunch of very good applications for your consideration.
