Recently active topics in Get Satisfaction tagged with authors

In my previous idea I discovered that your dashboard feed provides updates for the topics you are following. Since that is the case, I wanted to ask how possible to it would be to also have a feed with only your own actions.

The reason why such a feed is useful is generally for lifestream purposes.

Alternatively, it could also be useful if the author of each feed item could be given, it could also help a php hacker to separate the posts that do not come from himself. That would require an Atom feed though (which is of course, a better choice in general)

As an example of the problem this creates for me at the moment, you can see my current lifestream where it displayes action by everyone, and I have (seemingly) no possible way to filter it.
