I called myself 'The Irish Question' in homage to the great English politician (who lived in Wales) William Gladstone. In great frustration, he once said 'Every time I find the answer to the Irish Question, they change the Question'. Editing Wikipedia feels a bit like that. Every time an article seems to be getting somewhere, something new turns up to change it or improve it, or at least it does in the only fields I am interested in - History and Politics (including the history of politics).
Personal qualifications are irrelevant on Wikipedia, so I shall not bother to list mine. The only thing I am interested in is getting high-quality references into articles, and simultaneously removing the rubbishy ones, to ensure articles represent the scholarly position. Wikipedia, if used correctly, is a great tool for democratising knowledge. Unfortunately, it is too often used incorrectly as a form of personal advertising, the deliberate promotion of a false point of view, or attacks upon rivals or critics. I think we all have a duty to ensure such behaviour is kept to a minimum.
On a personal level, I am Welsh and live in England - almost the opposite of Gladstone.
