Provide some question examples

[waldyrious]

For example, the home page could say something like:

Type your question into the input box above and press enter. Or click one of the examples below:

• When was Elvis born?
• Where is the Eiffel tower?

And clicking the questions would automatically fill the search box and run the query.

Too late, they broke "Where is the Eiffel Tower?" too. The pattern "is located in" no longer matches any properties.

Yes, that might be useful. However, you may want to try http://askplatyp.us/ which is far more advanced than this simple tool which is merely a proof of concept.
