Not too long ago, for most of us, MapQuest was the default online mapping service. Even today, after a number of changes to its site, MapQuest is still one of the most popular places to get maps and directions online, even though other services like Google Maps or Microsoft's Bing Maps (formerly known as Live Maps) offer more features.

Today, MapQuest released its first iPhone app, MapQuest 4 Mobile (iTunes link), and after testing it for a while, it quickly became clear that MapQuest's app is a worthy challenger for the iPhone's built-in mapping application, which is based on Google Maps.

MapQuest was once the unquestioned leader among online mapping services. And while others like Google Maps or Microsoft's Live Search Maps offer a more modern interface and far more features than MapQuest, the latest data from Hitwise shows that MapQuest still commands almost 40% of the market. Even on the fast-moving Internet, old habits clearly only die very slowly.

The Google Maps team today rolled out yet another update. This time, they have decided to simplify the layout by putting more focus on the search form and taking away the tabs underneath it. Thanks to this update, the maps on the page get a bit more screen-estate and searching for directions has become a bit easier as well. This update comes just a few weeks after Google Maps added walking directions to its feature set.

The Google Maps team just announced the addition of a new feature to Google Maps: the ability to contribute to and edit maps through Google Map Maker. Users can now edit and moderate various map features, including roads, lakes, power lines, and bike trails among others.

While Google already allows users to create and share new map layers through 'My Maps', this is the first time it is actively looking for help in creating maps (almost) from the ground up.

Alright, who are you people? The people who still use MapQuest. You know who you are... my question to you is, why? According to the latest numbers from Hitwise, Google Maps is making significant inroads against market leader MapQuest. MapQuest still commands over 50% of the market, but Google is clearly the number two online map provider now, having passed and distanced itself from Yahoo! earlier this year. Shouldn't Google have taken over the lead a long time ago? What's the hold up?
