Fantasic idea and implementation. My timeline on here compared to twitter.com looks more sane and inteligent without those recommendations of 'X liked this tweet', and all the news topics. I assume that's because it's getting the raw feed.
I also love low-fi websites like this. I think websites shouldn't be a large drain on resources, and should embrace standard HTML as much as possible.
This has the opportunity to curve timewasting scrolling by making it more a periodical read. As such, I'd like the return of the timestamps and to implement hourly pagination, so that there's an 'end' point and a easy bookmark to start where you left off.
