My one big technical criticism is that interesting threads scroll off too quickly, before commentary has a chance to accumulate. The chronological most current threads contain too many duplications. Would it be possible to sort the threads by activity, rather than by time, keeping the most active threads on top?
Hopefully this will help:
In the News/Activism window, at the top and to the far right of your screen you should see the following links:
If you click on the word "Messages", you will be able to view threads listed by the most recent post.
Clicking on the word "Threads" will list each thread by the time the initial article or comment was posted.
