So I’ve not noticed this before, but it appears that YouTube now allows personalized homepages.
The new features included in our most recent site update are geared toward a more personalized experience for you. Check out the details…
NEW PERSONALIZED HOMEPAGE
Our goal is to give a simple answer to the question, “What should I watch today?” with a personalized, customizable homepage that makes it easy to find the videos and people that you care about. After reviewing results from our beta test and feedback from the community, we’re happy to now release the new personalized homepage to all logged-in users. Since launching the beta version in February, data has shown an increase in the number of users visiting the homepage, the frequency of visits, and the number of subscriptions users make over time. So, this optimized version of the homepage not only means a customizable experience for you, but more exposure for your cool videos and channels on YouTube (Note: if you are logged out or do not have an account you won’t be able see the personalized homepage).
IMPROVED EMAIL NOTIFICATIONS
The email messages you receive from YouTube have been updated with a new layout. In addition to a streamlined design and many wording changes, any comments or messages are now included directly within the body of the email, saving you time.
