Positive:

• Meetups have its own bar.
• Sizable karma buttons.
• No visible difference between promoted and unpromoted posts. I suppose that promotedness biases my choice what to read.
• Header design. Looks cleaner now (although the old design was certainly not bad).
• ETA: Retracting instead of deleting.

Not sure about:

• Not clear what nearby means when attributed to a meetup. I see Melbourne, which is on the opposite side of the globe.
• Icons instead of words.
• Dropdown menus.
• Graphical distinction between new and read comments. I like the idea, dislike the way it looks.

Negative:

• Own user name in all caps. What's the reason?
• Blank lines separating comments in the recent comments and posts bars. Needs more scrolling and reduces the amount of visible information. The items are already visibly separated by colour and bold font, there is no need for those gaps.
• Too large indentation of nested comments.
