We had wanted to remove the calendar link which was unused/didn't go past 2006 as well as replace FAQ with bugzilla/wiki.
The new posts was being fickle, but you're right it probably just seems more fickle for those of us who are here everyday, the con's were:
1) Doesn't work when not logged in.
2) Depending on your timing it wasn't showing new content even when that content happened today.
3) Because of 2, today's gave people more opportunity to see what people need help with.
Todays is already under quick-links, so I guess that's 2 votes for switching it back, will do
