Having the all Members show by default on Activity Stream

I have noticed that with I click on my activity tab it goes to the sites activity stream but tends to show only my activity versus the sites activity. Located here -- http://crosseyedgaming.com/activity

I have to click on the All Members like to see what's going on for the site. this makes the site look like not much is happening.

Is this normal?
And can it be set to show all members by default?

Thanks.
