If people are still looking for it, then post your reply where people are currently asking for it. Yes, you can post, but it's not cool to dig up 5yo threads to post a link to your blog, especially with your 4th post. I would have deleted it if it were a major violation, but instead I pointed out to you that it was a very old thread.
It seems you created an account here just to post links to your blog even though your blog doesn't really answer the questions in these threads. Your blog is very short and not very easy to read. All you need to say in your blog is that rules only fire on a change to a field, so it of course makes no sense to put a rule on a field that doesn't change. You always put the action rule on the field that is going to change, and then that change triggers the rest. This is a basic, fundamental aspect of InfoPath rules.
