My activitystream_identicagroup module is included with activitystream_identica as a submodule. You may still want to use my view to dress it up a bit -- that will be contributed upstream when I have time. If you previously downloaded and installed activitystream_identicagroup from my blog post, you should disable it and delete it from your modules directery before installing/upgrading to activitystream_identica version 1.1.

If you've tried activitystream_identicagroup module for Drupal, but still don't love the display, here's what I did for Frog and Owl: I installed and enabled activitystream_identicagroup module, then edited one user's settings to add frogandowl group to their activitystream. Note please that the identica field (if enabled) and identica group field are totally different things -- identica group is toward the bottom of the form. Then, I created a view for what I thought was a nicer-looking identicagroup block.
