My thoughts after visiting the site, in order:
1. Cool, I didn't know that fact
2. This is a nice, simple site
3. Maybe I should make it my New Tab page...
4. Where are the other facts -- can I browse them somehow? I want to see how good they are and if they align with my interests
5. Oh, there's no history, I guess this is the first fact, weird
6. scroll down Oh, this is a thinly veiled AD for a web dev studio...
7. Hm, there's more words, design effort, and attention put into the AD than the main content of the page
8. It's weird I had to scroll to see that it was an AD
9. Oh, they're being tricky and making sure the ad part is always below the fold using `height: 100vh` in their CSS
10. That's tricky -- they're hoping to get a ton of upvotes on HN before too many people realize it's an AD
11. If only they'd waited a few days to submit this to HN and had a few items in history, I probably would've made it my New Tab page and upvoted it...
