I do read the SO blog, and I roughly read meta, but I'm still often surprised by unexpected changes or additions of features. It appears that documenting is not exactly a forte of the SO team, and this makes it difficult to be up-to-date on the system itself.
Don't get me wrong, I really do like your improvements, and I also noticed that very important matters (e.g. rep rule changes) are announced in advance and quite well described. But judging from the related questions, there is indeed a decent amount of confusion caused by missing documentation.
Would it be possible for you, dear SO team, to update the FAQ pages and write a detailed changelog more often?
