Your logo in your nav bar is way too small, it's practically unreadable. I have no idea what I'd want/need an invite code and yet I'm being asked for one if I want to sign up. There is nothing on the home page that lets me see anything about how this product looks or behaves.

Pages seem kind of slow to load, it takes about 5 seconds to render each page in the "explore timelines section". Each page is also really heavy at like 4.5MB, several times larger than an image gallery site I frequent. Probably contributes to the slow load times.

Also, I don't really see any times on the timelines.
