These days, I am not very active on Wikipedia. Feel free to email me for a quick response.
I joined Wikipedia three or so years ago but have not been active for a while. My purpose on Wikipedia is to help maintain and expand articles so that they are of the best possible quality, informative, interesting, and free of bias. I will lend what analysis I can to community discussion and will try to improve Wikipedia's overall design, look, and feel. I'm a student, and my time is limited, but hopefully Wikipedia will be something I can keep up with.
I like to think of myself as a dynamic individual who constantly changes - hopefully for the better. If there is any label you could put on me, it would be skeptical. I won't accept a claim as true until I have a reason to.
Don't allow redundant "spell checker" bots, as this could be very inefficient. Instead, organize a system of concerted, non-overlapping bots who check spelling in an efficient and non-obtrusive way.
A section called "Conclusion" is inappropriate in a Wikipedia article. Such a subheadings is by nature POV and original research.
Some of these are probably impossible:
Normalize everything under one domain. (For example, en.wikimedia.org, es.wikipedia.wikimedia.org, de.commons.wikimedia.org...)
Continue to allow, say, wikipedia.com to redirect to the appropriate page.
Under the new domain system, change the user system so that user pages/edits/contributions are all one a single page, if the user desires. (For example: wikimedia.org/User:John.) This would involve some kind of normalization as well. 3NF is your friend.
