About a month ago, I adopted an answering style from Thaddeus of Science Fiction & Fantasy Stack Exchange. The new format uses bullet points below a level 3 header with a brief summary of the content. The idea is to make key points stand out:

...Go for smaller chunks of text, isolate the main points, use section headers to break out big ideas, or specific vendors... —Thaddeus (source)

Until now, I have not run into an issue with this format and answers using this format have been very well received.

The header in this answer was formatted out by a fellow user who believed that the headers were shouting, and at least one moderator agrees with the edit. However, this is inconsistent with the feedback I've received from other users, such as by voting and in this chat room.

Is it okay to use headers in this manner? If not, what alternatives should I consider?
