Howdy,
I edit content in my subject area (algebra), and perform technical edits on recently changed or created articles. I like peaceful collaboration on content, and unnoticed technical improvements.
Wikipedia allows both content providers and technical editors to work together. Content providers lend their invaluable expertise to wikipedia by composing the core of the articles. Technical editors save content providers from worrying about essential tasks such as minor editing and technical wiki markup.
I tend to think content providing should be left up to subject experts, and so only contribute content to algebra articles. However, wikipedia is a huge place and I enjoy helping with technical editing in a variety of contexts. I firmly believe in the utility of categories and the importance of not WP:BITEing new editors, so I enjoy doing new pages patrol, especially to categorize new pages and help new content providers understand the wikipedia process. I also believe firmly in the necessity of WP:RS reliable sources, and so spend time WP:V verifying articles in my subject area.
I like to collaborate on articles, so I tend to edit recently edited articles. I firmly believe in consensus, and follow WP:1RR by discussing changes on talk pages and modifying edits rather than reverting them. I definitely make mistakes in technical editing, and certainly make some suboptimal content edits. When I do this to an article you're working on, just leave me a note on my talk page, but please be nice.
