I have noticed that the comments feature from FriendFeed has had a mixed response regarding how it is rendered in AlertThingy.

Here is my recommendation. When a new comment is posted FriendFeed should have an option to just show the most recent comment that has moved it to the top of the list of updates and hide the rest.

Showing all the comments on a long comment thread will bury all the rest of the updates and create an endless list to scroll. To resolve this I recommend an option to show just the most recent comment, that way we know what pushed that post to the top of the list.To see the rest of the comments we can use the button as usual.
