HaloScan

This is the service that allows me to have comments and trackbacks for every entry.
Pros:
Free,
Easy to set-up,
Comments and trackback capabilities,
More control for me to manage comments (I can erase things that are mean and nasty),
Good troubleshooting help (including a forum for discussions)
Cons:
Confirms suspicions that no one actually reads my site or cares what I write.
Here's the link to HaloScan...there's also a button on the bottom of the page.
