From what I can tell, there are several different versions of how this can be handled. My friend did a 'whirlwind' tour of 22 blogs in 21 days. His critique: Wow. Intense.
Seems he was on a new blog each day - well, there were 2 days when he wasn't on any blog - so he had to double up some of the other days. Anyway, when he was showcased on a blog, he made sure that he was available to reply and answer any questions that might be added in the comments. He told me it kept him hopping, especially when he was on two different blogs on the same day.
Another blog group decided to attempt an ambitious tour: Host a writer for a week on 1 blog and then move to the next blog with a total of 15 blogs currently in the mix. So, in actuality, the writer was being advertised, for all practical purposes, a total of 15 weeks... almost 4 months. If more blogs joined, then the author would continue on until they all had been visited. Talk about exposure.
But what exactly does the writer do for a blog?
From what I've been able to discover -- the author has different possible scenarios. One site wants an interview to learn about the author. Another wants to detail the book(s). While another may just want the writer's thoughts on the craft.
I've never done a blog tour but I have been a guest on a couple of other blogs. I've done the interview and I don't think that I'm all that exciting. I attempt to give a snappy response and show my "fun" side, sometimes it just doesn't work.

And, now, the question that everyone has been waiting for the answer to--
Question: Are they any good?
Answer: Perspective. What are you expecting or hope to accomplish. Sales? Recognition? Presence? Each of those, in and of themselves, have their own reward. Maybe sales will increase. Maybe people will come to know your name. Hey, you might even get a fan base created for having a presence. Only you, the one who goes on a blog tour can decide if they are any good.
Until next I ramble on...
