Have you ever been to MSN, Google or Yahoo and seen a “personalized” message pop up?
The picture above shows a message that [MSN](http://www.msn.com) displayed to me. MSN noticed that Live Search was not the default search feature in FireFox and the purpose of this message was to convince me to add it. Not too many sites have implemented anything like this; it could be a great way to monetize social media traffic. If someone came from [Digg](http://www.pronetadvertising.com/articles/beginners-guide-to-digg.html) you could display a personalized message that may appeal to them and actually increase your conversion rate by encouraging these visitors from Digg do something meaningful on your website.
Anyone have any thoughts on this?
