I have never been a very active editor of the English Wikipedia. First, my English isn't perfect, especially my active language skills aren't. When I compose complicated sentences (those you are likely to encounter in an encyclopaedia), they are often awkward, out of place, or just wrong. Second, at more than 5 million articles, this project barely needs my support. It's big enough. Third, this Wikipedia contains a huge sea of rules and guidelines that hinder me from making major edits. It's likely to be either removed or severely altered anyway. Moreover, these conventions include several rules I flatly disagree with. For instance, some people won't cease littering articles with 'citation needed' tags (sometimes every single item of a bulleted list - man, you made your point, okay?) and don't even think of improving the articles themselves. That annoys me.
Still, I am an avid reader of this project, which besides a source of irritation is of course an endless source of information as well. I often base my own articles elsewhere on English Wikipedia pages, and I often spend spare time reading articles. By doing so, I occasionally come across typos, errors, and gaps in articles, which I may correct and/or amend. This is reflected in my contributions.
