YouTube recently upgraded to the new One Channel design. The new design emphasizes responsive layouts for mobile devices, tablets, desktops and laptops, and TVs. A single banner on a white background replaces a customizable background and color scheme. YouTube recommends using a single 2560 x 1440 px image that fits its template. The featured video has been replaced by a Channel trailer for non-subscribers. Think of it as a short video that welcomes people to your Channel and tells them what it is about and why they should subscribe.
To enhance security, Twitter now offers two-step verification. The release of the new feature follows several high-profile account breaches – including a false tweet sent from the Associated Press’s Twitter account in April. If you chose to enable the two-step verification feature, Twitter sends a text message with a unique code to a cell phone that must be entered to continue the login process. This extra step is simple and provides another important layer of protection for your account.
