Update
If you want to submit any more categories throughout the year, until the last few weeks of the year, you can still do so by answering this question. If a category here gains net score > 3, I will add it as a category accepting nominations.
After good meta consensus with only some minor and fixable problems, the Best Of CGCC nominations process is changing for 2023.
In this thread, we'll consolidate the categories for our Best Posts for 2023, and then we'll open nominations for posts in each category. Nominations will remain open throughout the year, and voting will be in the first week of January 2024. Unlike in previous years, in this thread, we are only looking for categories, not bounties (yet). Bounties can be offered to reward the winners in those categories at the same time voting goes live.
Please nominate categories as answers to this question. Each answer should contain a category to classify exceptional posts from 2023 (e.g. Best Mathematical Insight or Rookie of the Year). The top-voted categories will then receive separate nomination posts to find the actual winners. Like previous years, I'm not going to state a fixed number of categories that will make it, but it's probably going to be between 5 and 15, which is what we've usually gone with in previous years.
Feel free to resubmit categories from last year or previous years, regardless of whether they were among the final selected categories or not.
Voting on categories should last around 2 weeks, but this is by no means a hard limit, and we'll be happy to extend it further if new category suggestions are still incoming.
