I've often commented on my wish for the Silverlight team to focus a little more on Search Engine Optimisation (and printing support....but that's a topic for another day) as I feel that this is one area that could put off a lot of business users (yes you can argue that it is an application and if your application is content rich then possibly your application should be built in asp.net with occassional use of Silverlight to add "islands of richness").
There are ways of having a search engine friendly Silverlight application (my plan was to have something more solid by now but life has been busy...it is however still on my todo list :D) but I was/am hoping that it does get some attention either now or in the near future.
Looks like Adobe are aiming to do this
