Systemic bias
I have signed up with the 'systemic bias' project here; not because I necessarily agree with everything that is said about bias under that heading (still less, with what could be hung on the peg), but because it does seem likely that bias will be a long term issue for WP.
The business about pictures with everything, for example for featured articles, does seem to be a bias of the systemic kind. Obviously a person's importance is not to be judged, mainly, on how easy it is to have a photo of them on the site.

Mathematics
I've been adding material here from a previous existence as a mathematician, on a hobby basis.
Useful link: list of mathematical topics (lists), to find any maths stuff. Also
I wrote Wikipedia:Naming conventions (theorems), which seemed to be needed.

A bit about me
Officially, my interest has been go (board game) for about a decade. For which see my writing at Sensei's Library and at gobase. Wikipedians who have also played me at go include Matthew Woodcraft, Jitse Niesen and William Connolley=William Connolley; I've also met Paul Erdös, Frank Adams, Richard Borcherds, Elwyn Berlekamp and Ross Anderson over the board.
Before that, I had a time working on the theoretical end of functional programming. I'm supposed to be writing about something quite else, at present. Details of my semi-brilliant mathematical career on the user talk page (moved now to User talk:Charles Matthews/About me), at someone's request.
Attendee at the meet-up in London June 5 and the meet-up December 3.
