It might be useful to have a alternate view mode that lists one line per conversation with the title, the original date, the # of comments, the date of the last comment and maybe the tags. Maybe if you hover over the topic it opens it up so you can see the text.

Currently I can see about 4 conversations and then I need to press View All to see more. Since these are sorted by date entered, not date last updated, the top 4 aren't necessarily the only ones that might be of interest.
