Living just off the Danforth, we approach TOTD weekend every year with a bit of dread. We know that we can't move our cars starting Thursday night (we're near the subway, though, so we're hardly stranded), and we know that we can look forward to souvlaki wrappers and drink cans scattered on our lawn each morning.
Having said that, we wouldn't mind the inconvenience if TOTD were a bit more interesting. But, frankly, the Danforth is so much more pleasurable without the crowds of TOTD. And there isn't much at TOTD to grab one's attention, besides eating. Too many booths dedicated to corporate sponsors -- as someone mentioned above, it's great if you are shopping around for VoIP or a mortgage, but otherwise it's incredibly dull street festival fare. They need more street performers, more entertainment, more street merchants, artists ... something.
As for the crowds -- yes, there are too many people. I don't really know what they can do about that.
I must comment on the post above, however, which suggested that one needs to spend 20 minutes in line to get food. Living nearby, we tend to walk down to the Danforth throughout TOTD weekend to grab a snack, a quick lunch, dinner, etc. -- often at peak times. Some booths have line-ups, some booths have none. It never takes us more than 3 or 4 minutes to get our food.
