I signed up for it sometime last week. Created an account, subbed to about 50 channels and organized them with the categories you can make. Well, unfortunately I guess there was some bug where logging in and viewing trending and feed was happening. Submitted a bug report with details, one other also had the issue, within 2 days they said there was a fix out. Within 14 hours after that I saw the reflected changes! Was able to login to my account again and everything was still there. Been rock solid ever since!
