Several people have mentioned that we should note significant answers to common (or interesting) questions, for example herehere.
I think a community blog 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).
