1. Yup, the "at" is basically for the regular season pro teams in American sports. We'll be fixing this soon for all other situations 2. If the guy was your friend, would that be more useful? Like in real life? 3. The server is OK, we haven't implemented any polling yet to the page. It started off as a quick check-in, leave, and come back tool early on. Our roadmap includes a smart decaying poller that will update the page often. A lot of our users now just refresh, nobody's complained too much yet, but we definitely need to get that in ASAP. 4. Definitely need something that says: "You can be anywhere!"
Thank you for trying it out and giving us the feedback even though you aren't a huge sport fan. We appreciate it!! Hopefully we can cover more big events like World Cup, Olympics, Formula 1, etc. where you'll use it.
