Plugin that allows visitors to place pins with comments on a map?

Hello.

I am desperately looking for a map plugin, where visitors can mark and comment locations. Eventually also Rate (restaurants, cinemas…).

All plugins that I found until now, do the same.
The site operator inserts a map with pins in an article.
This is Web 1.0.
I want “Web 2.0”. The visitors should put pins and commenting.

Many people want such a plugin.
There are many ways to use it.
Among the various topics.

If there is no such plugin, I hope that a programmer writes a plugin.
You can do something that no other plugins offer.

What are the best maps plugins?
I could ask the programmers to extend their plugin.

Thanks,
Tobias Claren
