This post is about web design rather than Google Earth design.
How to lose viewers: So I wanted to watch Al Gore's speech to the democratic convention, here's the official link. If you go there with Firefox 2 without the right plugin it asks you to download one. Doh! democrats, if you want to get people to watch your speeches then don't make them download a special plugin, hoards of them will not bother. Look on Youtube and of course, the speech is there for all to see using flash, which pretty much everyone has.
