1. I love the keys for badges.

2. I'm not fond of the circles for answers, though. I prefer, as someone else mentioned, the idea of cylinders for answers.

3. Also, like many have mentioned, the logo is nice, but not [unique](http://www.google.com/search?q=database&tbm=isch). I hate criticizing it, though, since I don't have anything helpful to say on how to change it.

 And when I do try to improve on the logo, I end up with [this](https://i.sstatic.net/j6iOo.png), which isn't any better. ;)


Other than that, I really like it.
