Don't look at (so far)...

... floating member menu. Still at the early stage of development, this menu will feature AJAX-based Quick-IM, Presence, Friends Tracker, Alerts Tracker, Fast Mail, and more. It can be put on top and can be "frozen" there, by the way.

... OpenID support is still under development

... Google OpenSocial is already in, but not quite in full, so give it some time

... Facebook Apps support is still at the early development stage, so you can't see it

... see more Profile customization is going to be in as well, better than ever but not yet

... Couple Profiles are working now, but still need some thought and time

.. searches: keyword search, people search, quick search (and more planned)

maybe you missed the last 2 lines ^^^^^
