Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep going, but it does probably need a differentiator to be interesting.
Consider placing link to the catalog/places right on the main page, otherwise it is not that intuitive to discover where it is!
The data is initially crowd sourced, or researched by me when I'm bored. Keeping things updated is done with various automated (and some manual) alive checks for each venue.
I know you're right about the landing page. Would be nice to show the closest venues or locations there immediately, but I absolutely loathe pages that ask for positional data right off the bat (could do some geoip stuff maybe).
