On the ticket searching page, I would expect it to be ajax goodness — yet it wants to keep reloading the full page for every option change. I don't like that.

On the ticket searching page, I would expect it to be ajax goodness — yet it wants to keep reloading the full page for every option change. I don't like that. The homepage — ticket buying visitors likely don't give a crap about anything but the search box and the "upcoming events" bit. Personally, I would treat the site as as just that — a site — rather than an app. Put some cool info and links to events on the homepage, to attract the people who are interested in what your service providers, but are not there exclusively for any tickets at that time; give them something to look at, and they will be more likely to return WHEN they need to buy tickets. Maybe your being too much like Google, how many times does the average person search a day — compared to how many times they buy tickets? People always have something to search for, so Google quickly gets people coming back. You on the other hand, have to try harder to get people to remember you.
