I'd like both, but last comment is most important to me. What do you think?

Currently in the topic summaries (trending/recent) steemit shows the date on which the original posting was made, but it doesn't show when the last comment was made about the post. While I like seeing the original posting date, I'd really like to see when the last comment was made about the post. This allows me to see if someone's posted a new comment to a topic I'm following and it also lets me know if the topic is still an active conversation that I might want to join.
