Good evening, this is Bono.
The deadline for Mashup Award9 is approaching.
I'm going to try my best to make one more step.

What we tried to do
Simply put, it's a map version of Tuttei goo! or Yahoo! Chiebukuro.
Most of these teaching sites are text-based, which makes it hard to ask when you want to ask in a place.
So we created a website where you can easily ask and answer questions on a map.
We plan to complete it a little more and submit it to Mashup Award9.
This time we used Google Maps. When you write a question and press the submit button on the form, the question is instantly displayed on the map.
You can also click on the pin to answer the question and see other people's past answers to that question.
Display the marker on the map

Using Ajax with cakePHP
If you use a framework like cakePHP, it is quite complicated to deal with errors when they occur, because you don't create the content yourself.
I was quite annoyed by this Ajax as well.
