-Try making the breadcrumb gray, black seems harsh.
-It is still too cramped - try moving the stories down a few pixels to give some breathing room to the time based filter.
- The "un-like" should be on the same line as "like this".
-Can you show me what the publisher looks like when I start typing?
-I like settings as a separate page (we need delete there)
-Something is not right with the upper left menu bar.  I think it is trying to do too much and becomes unclear.  My vote is to have that button say "Switch to a Different Group".  Next to it (on the left) we need a "Back to Connect Home" link.

It looks good, but we are missing the persistent angle.  We do the real time flow well in this model, but not the "show me the wiki pages in this group".  I think we need content based filtering on the right side.  This way if I want to see all the "announcements", "links", "files", "pages", I can get there in a very obvious way.

Should we have a call on this say today at 3pm?

I like the Connect switcher, as long as it controls paging groups nicely.

I'm not sure we need more filters. If anything, I wish we didn't have so many obvious ones. To find content, you click on the icon, e.g. click the icon of the wiki feed. Can't find it? Filter by time and try again.

I'd like to stay away from lots of filters, unless we can find a way to render an uber widget that slices and dices across all the dimensions we need from a single UI widget.

Ok... guys, I'd really like to close this out.  Can we meet this AM to finish this off?

Pretty Sweet!
