I'm Mistral, I liked LEGO as a kid and rediscovered the coolness of the brick some months ago when rebuilding old sets with missing instructions thanks to Peeron.
I'm currently building my own LEGO town/city, Diegoville, which is growing every week or so. It is mainly City/Town but with a mix of Castle and Pirates as well (my fav sets). You can check it out here (blog). I order from online shops or just from ebay (excellent way of getting older sets). Bricklink is way too overpriced!
I think of trying building MOCs in the near future (some interesting contests going on here)...
I once wanted to make brickfilms (animation) but never got around to it (time issues). As a result I ordered some (now sold out) Star Wars sets which was cool.
