Reddit.tv was an app to watch videos posted to reddit but shut down back in January. Haven't been able to find a replacement that I liked, so I built my own. Made the videos full-screen by default and added extra stuff like support for Soundcloud embeds (so you could listen to music subreddits), a directory of video-posting subreddits, multireddits, keyboard shortcuts.
UX idea: I'd make the subreddit list alphanumerical. I had to look through it a few times to find the subreddit I wanted.
Another UX idea: If a video/soundcloud fails to load, is it possible to detect that the tab isn't playing audio (say after 10-15 seconds) and skip to the next item in the list?
The subreddit list definitely needs some attention. The aim was to bucket them into categories, so I either need to flesh that out or sort them.
Skipping media that doesn't load is doable. Some content won't play or advance automatically because a lack of an api to control the api (gifs, Liveleak, Basecamp, iTunes, spotify) but I didn't automatically filter them out because a lot of it is good content. Probably a good option to add to a settings page.
I'd never heard of Reddit.tv.
That seems to be the general case, a lot of people never knew about it. I used it just as much as the homepage and it was a great way to just sit back and absorb content.
