I would like to suggest www.groupsense.com it is a bug tracking tool with social features. So you can follow bugs / people / projects.
So for e.g. You can follow a particular bug that you are interested in. Or you may follow a particular user who might have filled interesting bugs in the past.
You get an activity stream from the bugs/people/projects that you are following.
I am one of the co-founders so take it with a grain of salt.
I would be happy to hand hold you to implement this and add features if you need them.
Send me an email at [email protected] I promise you it is a new software but we have been using it internally for over a year it is stable and you will love it when in 15 seconds everyday you will be able to look at your activity stream and exactly know what is happening.
Just over the top of my head over the last 16 years I must have written a million lines of code but have sold nothing.
Gotta crack this nut !!
