Right now Twitch's interface makes uploaded videos almost invisible. In order to find uploaded videos, you either have to find them at the bottom of the search results or, when in a specific game, you need to go to a separate "uploaded" videos tab.

While I do not want to suggest specifically stealing from Youtube, I think an interface redesign needs to be considered to make uploaded videos more visible. I think that the focus should be on what's live, but that there should still be quite a bit of visibility added to the uploaded videos in both search results and games listing. Whether that's an integrated pool showing both or perhaps making a single unified page giving listings of live content as well as uploaded content, improvements are needed here.

Right now, the only ways of notifying your followers of an upload are through e-mail and channel feed. Not everyone wants to spam their followers e-mails (potentially causing them to drift away) and not everybody uses channel feed. There should be a proper dashboard that displays all the videos that have been recently uploaded from the broadcasters you follow, and only uploads. Currently, if you go to a channels videos, you have to specifically filter for "uploads," otherwise they're lost in the sea of 100's of VOD's and highlights. In this dashboard, there should also be discovery mechanisms. IE: Popular videos from recently watched games, recommended videos, popular videos from certain categories, etc... It's too out of the way and convoluted to properly upload videos while expecting them to get views.
