Ouch, I became a Labutnum this week. About time to find a Wikipedia Anonymous somewhere and/or say something about myself. Looking back at my contributions, I seem to have an interest in categorizing, adding people's birth/death data, and starting/expanding articles for obscure or strangely underrated cartographers, explorers and explorations, geneticists and biologists, clades, mountains, etc. Especially so when they are Dutch (mountains). The least unsung person I've started a bio for is probably Esther Vergeer, which bio someone else agreed was overdue. The most underheralded person whose stubby bio I want to expand is that of Jan Ingenhousz. Saving the House of Habsburg for another 150 years and discovering the most important chemical process on earth apparently can't keep you from obscurity.
Otherwise it seems I'm into creating definitive lists of more or less esoteric subjects like Dutch painters, concertos for English horn, oboe quintets, oboists, the strongest football nations of the last half century (a valid one!), and the highest mountains of Africa, New Guinea, New Zealand and the Alps. The last one in three parts as it got way to big for a wikipedia page. Only two of my lists are in the wikipedia top 10,000 visited pages: the List of highest mountains on earth and the List of most expensive paintings. Careful, the last one may make you feel a bit ill.
