Several people have mentioned that we should note significant answers to common (or interesting) questions, for example [here](https://chemistry.stackexchange.com/a/27418/5017).

I think a [community blog](http://blog.stackexchange.com/2011/06/blog-overflow/) could serve several great uses:

* Discussing interesting topics in chemistry outside the scope of question-and-answer, like news of Nobel prizes.
* Highlighting notable developments in recent chemistry research
* Highlighting chemical education topics
* Highlighting awesome answers and interesting questions.

I think the key components would be defining the scope and getting 4-5 people to post regularly (e.g., 1-3 posts per week).
