Is a comment!
This isn't the start of a series, just a small piece of advice.
Dear New Bloggers,
You want to have comments on your posts because then your blog doesn't feel as empty so don't make us commenters, who are willing to take the time to comment, jump through so many hoops. Jumping through hoops makes people less likely to comment, which you as a new blog can't afford.
You are a NEW blog you're not going to get much spam. I have as yet to get ANY spam despite allowing anonymous comments without an 'Are you human?' test.
When you get to be a big blog, then you can afford to put lots more moderation on your comments. For now, stick to EASY AS POSSIBLE.
