I use both and both have strength and weakness. (I wonder why Yahoo and MSN are so dumb not to study the competitor's strength and improve own product)\n\nMSN:\n1. status clear - it shows offline when it is offline and online when it is online. When there is a message that doesn't go through, it tells you.\n2. It is relatively harder to sign in compared to Yahoo.\n3. No offline message ability\n4. extremely convenient control on each of your pal\n\nYahoo:\n1. Status unclear - we don't know whether some of our messages to through or not.\n2. Very easy to sign in - one can detect this if one is using a connection with really low bandwidth\n3. Offline message ability\n4. more steps to have control on pals in contact list\n\nMore... let's explore some more...
When Yahoo and MSN talk to each other...which one will u use? and Why?
