as the default view, have it show 'Postings' and your stuff you do on the site. So people that check out your page can see what you've done, uploaded, posted, liked, followed. You can catch up with someones activity by viewing their page. Setting can be adjusted in the privacy page to set who can view this info obviously. This is another way that your site gets 'content' Friends tuning in to see what else their friends are doing and maybe they'd be interested in checking out as well.
