Many wikis have userboxes that you can use on your user page to express certain interests and preferences. Ask the community on your wiki if they have these, or look in the template namespace for options.

Some people add information about themselves, possibly including contact information and information about their areas of expertise and interest, likes and dislikes and so on.

You can use your user page to help you to use a wiki more effectively: to list "to do" information, works in progress, reminders, useful links, and so forth.
