Thanks for the notes and suggestions.
We do intend/hope to do Canadian websites as well as websites from many countries around the world. We are taking it slow at the start because have a few things we are trying to get right:
(1) We want to get the technology right to make sure that we can crawl things accurately. If we were doing a Google type search, it would be easier but when we are also trying to identify names, dates, events, and places, it is fairly complicated.
(2) We want to get the experience right so it is easy to use and helpful to both users and publishers.
(3) We need to understand the laws in different countries as it applies to crawling and displaying data. This is the primary reason we are not doing websites outside the US, yet. Our legal team wants to do an analysis of local laws to make sure we do things right.
I hope that helps.
