We have updated the site style again. We have simplified the row style so it a bit less busy and the overall look has changed to allow a clear distinction between the stream and the activity column. The context menu is now available by clicking on a friend's picture (instead of the pencil icon). We now also support grouping all a person's activity, so that if they post a Twitter update at shortly after a Facebook (or the same time) they will now be grouped.
Finally, we are preparing for a public beta launch which should happen on the 1st of September.
