I just found out that I have not been using Yahoo! services like Mail, Geocities, Games, Messenger, and most importantly the Yahoo! main search engine (or main Yahoo! site) for a long long really long time. The answer is simple, Yahoo! loves those Flash banner ads so much that user experience is no longer a priority. Did they set user experience as a priority before? "You have to love our Award-winning Hyper Slow Service Plus Gigantic and Slowest Loading Flash Banner ads if you want to use our free services, otherwise please get out from Yahoo!" Yahoo! says this indirectly to all its users everytime they load Yahoo.com.
I hated the new system, I stuck with it for a couple of months but the speed the number of timesouts I was getting made me switch back.
