Thank you everyone for your feedback, it's very motivating to see that so many people find this project interesting. I might turn this into a Show HN soon, once the site fills up with some interesting predictions.
On the technical side, the logs show over 6600 unique visitors in the last 12 hours, with over 1100 of them (and 18k requests) during the busiest hour. I know that's not too impressive, but it's still good to see the basic VPS running the server didn't break a sweat (load average peaked at around 0.1).
In the mean time feel free to post content you're interested in, and also contact me (e-mail is in my profile) if you have any feedback. Thanks again!
