This is like the 2nd or 3rd update in the last year. Anyway, its still easy to use and the colours are good!
new look is cleaner.. MUCH less clutter.. and the reason they keep re-designing it.. is they are trying to monetize the thing.,.. (imho) last I remember reading was they can barley afford the server costs
i've tested it as a beta user month ago. i like the old one really. and i still can create i think a group in the old theme.
