Have fun
Really! This is not some stodgy display; it's a bunch of people reading and writing about what they are interested in.
Add fun notes to things you read.
Put a question on one of the pages, or the Wiki FAQ.
Make a page about something that interests you.
Make a page about yourself (you can link to it from the People page and elsewhere if you like.)
