I've enjoyed playing around with Insight.

What genius to have provided both Windows-style and standalone installation options! I can take Insight along on Web-marketing sales calls without even bringing a laptop. Thanks a million!

I'm surprised that Insight analyzes one page at a time in order to assemble the complete site report. I'd expected it to traverse the whole site automatically. A feature for the future perhaps? Concerned about getting stuck in a cycle?

That feature is slated for version 3. Doing an entire website along with all those checks is a huge undertaking that needs to be carefully planned out.
