Let's not get too personal
When contributing new content, please remember that the entry is part of a wiki, not a forum. The user shouldn't have to work through a sequence of entries to learn about a topic - there should be one entry that's constantly developing. People will be reluctant to modify an entry that has someone's name placed prominently at the top, or that is written in the first person throughout (that is, always saying "I") - such an entry reads like a personal diary that shouldn't be interfered with!
This will explain some modifications I will be making to the style of some recent entries.
Of course, I'm anxious that everyone's contributions should be fully acknowledged. Users can always see who first posted a topic, who made particular revisions, etc., by looking at the page history. I shall put occasional notes at the top of some pages drawing users' attention to this.
