Notice that there are two sets of comments boxes now? The first comments plugin I chose wants to bilk me for $4 per month to have more than ten comments and more than five email notifications of comment activity. I've no idea if that means ten comments total, or ten per page, and likewise for the 5 emails. Sheesh.
The Facebook comment box is free and unlimited. I'll pay Wix for this website when they have their own native blog comments app that doesn't require FB or Disqus accounts or add-on fees. Did I mention 'sheesh'?
