Since that posting the application has gone through a slight overhaul. It was originally a Flex app and has now been ported to HTML, with a few feature enhancements baked in.

I spoke with Keith Harris, one of When Is Good's developers, on the decision to move from Flex back to HTML. Keith indicated that the change was mostly due to Flash's inherent load time:

"Considering our main competition is people simply emailing each other to work out when they are free to meet up, we define our product on the amount of time you save. Waiting up to a minute to get the swf to load kills our entire proposition stone dead. The rebuild moves a lot of the processing back on the server and our users get their pages just as quick as their connection can supply them."

There are certainly ways that Flex users can mitigate these problems - techniques to reduce swf size, storing the framework in an RSL, etc. - but for an application as simple as When Is Good it's just not necessary. In my original post I said that without any of Flex's rich features, When is good makes more sense in HTML. I'm glad to see that Keith agrees, and I think the application is better for it.
