I started playing around with Google Maps Engine to see if it provides a nice environment for creating and storing cache information in an online mapping tool. Spoiler alert: it does.
While meant more for business use, you can also use the Map Engines Lite version for free. It's a great way to create and share your own personalized maps.
In the example below, I used GSAK to export a CSV file containing a filtered list of the most difficult caches (D/T rating > 4.0/4.0) in my neck of the woods. Then I simply imported that file into my GME account, and presto, a share-able, customizable map.
