Update 1-18-10: I have temporarily(?) disabled this plugin. Read the comments.
When you read my RSS feed, you’ll now see the number of comments in each post. So a title might read:
It Was on Fire When I Got Here (3 comments)
I installed this because comments are so very important but you’d easily miss them when reading just the RSS feed.
I encourage all my friends to install this very small plugin! It’s just 7 lines of code. :-)
