Whether you want to call it "2.0" or not, the fact is that a better, stronger, faster Web experience is quickly replacing the old one, and there's a lot out there to be psyched about. But, for every Google Maps, Facebook and Flickr that does (most) everything right, there are a thousand more Web sites out there still clinging to archaic, annoying and even deceptive practices. What the operators of these sites fail to understand is that forcing me to endure these "experiences" is worse than not having a Web site at all.
Mapquest and Yahoo Maps are slow. Google Local's maps pop up almost immediately and allow you to click and drag to scroll around without waiting for a new page to load. Google bypasses the traditional bottleneck-building the map on a server and then transferring it-by instead sending your computer several small map "tiles" with instructions for assembly. When you scroll, it sends new tiles rather than a whole new map. Google also released the code behind the site, inspiring users to create dozens of applications with it, including chicagocrime.org, which plots reported crimes.
