Facebook and Twitter each received noticeable updates today. After a three month beta, Facebook Gifts is now available to all users. Accessed at Facebook.com/Gifts, you’re now able to purchase real-life gifts for your Facebook friends, from companies like babyGap or ProFlowers, or digital gifts, like iTunes gift cards. Even better, you can donate to various charities on behalf of your friends, like the Robin Hood Foundation’s Hurricane Sandy relief efforts. Twitter, meanwhile, has made header photos mandatory for all users, starting today. Like Facebook Gifts, this has been a feature available to users for a few months. To make sure you’re not caught without a great header photo, click on the Settings icon on Twitter.com, or tap the Me tab on your mobile device. Click edit profile, and you’ll be able to upload your header picture. Choose a photo you’d like to feature prominently at the top of your page, scale it to make it look perfect, and you’re done!
