We apologize for any difficulties you had accessing the site yesterday. A server update ended up taking much longer than expected and, unfortunately, erased some data that necessitated going to the most recent back-up. So if you marked some items read, saved them, etc., and aren't seeing that reflected you know why.
Everything should be getting caught back up today, however we have a lingering with scoring items and grouping so if you use the Interesting view you won't have anything new there yet. We'll get that fixed ASAP.
Thanks for your patience.
