I started it on December 2014, with a pretty ugly interface and only three maps available (World, USA and Europe). I already had some success on Reddit, where I created interesting map charts with it (like religiosity by US state, most popular browser by country,etc.) and shared the link to the site in the comment. This got me many users that would either come directly from the Reddit post or see another map somewhere and google my site. The big spike came last May, when I shared it on /r/InternetIsBeautiful (https://www.reddit.com/r/InternetIsBeautiful/comments/4jcadt/make_your_own_custom_map_of_world_europe_the/ https://www.reddit.com/r/InternetIsBeautiful/comments/4jcadt...) , which is a specific subreddit for internet tools and single-purpose website, and it propelled to the front page.
