Hey! You noticed. Things were getting a bit too wonky with the site design, so we did a hard reset to make the site a little cleaner and easier to use.
The only "new new" thing is the Latest Activity page at the top of http://brooklynian.com/forum/ - it's designed to be a little less boxy and to emphasize the most recent comment on the post (rather than the original post itself).
There are bound to be issues with the new design, missing features that still need to be added back in, etc. Let us know what you think in the comments.
