I have been editing Wikipedia on and off since 2006, mostly in historical articles. As much as I'd like to properly write some full articles, I find I rarely have the time so seem to spend most of my time tidying and amending.
I have a personal loathing for two elements of Wikipedia. Firstly, biased editors who hide behind policy to ensure that certian articles don't represent the truth (cf The Daily Mail), as well as the apparent need to relate every single Wikipedia article to Star Trek.
I dearly wish I was more technically savvy, and could create this kind of user page myself. Instead I nicked the template, with many thanks, from Miesianiacal.
