Twitch, now one of the most popular streaming sites on the web, has announced a partnership with Steam. Currently this partnership will allow Steam users to connect their accounts to Twitch and be eligible to receive rewards from watching paid events for Dota 2, a bonus that previously required users to use in-game streaming. This will most likely prove useful for those away from home or on less-powerful PCs, and really only opens up possibilities for streaming as a whole.
Steam users looking to link their accounts to their Twitch profiles (or vice versa) can find an option in the “Connections” tab.
