You're right- we didnt focus on the ability to see maps that others have made. We reckoned that until we get a particular user base, pretending like Linkwok has a network effect would be a waste of time and resources. Right now, there is a very small hook to make this point- one of the search engines listed is Linkwok- where you can search for maps that others have made. We have metatags and other stuff built and kept ready so that the maps can be trawled by Google and other engines too. We expected that this 'ecosystem' would come into its own after we had some solid traction and focusing on that instead of creating traction might be a waste of resources today.

As for use cases, a common one would be planning a holiday with your significant other or friends- more time goes in communicating suggestions and feedback over email, Word files and the like- Linkwok would be an easy platform to send these back and forth. Here's an example: https://app.linkwok.com/map?id=cWzkjEghEgtqewHuP

Another example is creating an at a glance overview of something complicated, namely the mess of kingdoms in George RR MArtin's Game of Thrones series: https://app.linkwok.com/map?id=cWzkjEghEgtqewHuP

Teachers can also use Linkwok to give more information about a topic. Here's an example where a friend wanted to teach his class about the history of Linux: https://app.linkwok.com/map?id=gNEtYqPbJyacbEfmd

As for the number of searches, http://www.statisticbrain.com/google-searches/

And you're right- search engines do a great job of giving you an answer, as long as the answer is encapsulated within one statistic (weather in NYC, Welsh corgi personality, etc) but anything that requires even a modicum of research, finding the 'right' site is increasingly more difficult...
