Please Ignore question 1. Sorry, I thought the example of how to check and compare revisions was actually MY draft. So embarrassing. I saw the Buckshot etc post as a revision to Where Now.
I did refer to the Buckshot post in February, which must have meant it was active at that time, since I create a link by first going to that particular post in my blog and opening it.
This means that the Buckshot post was still up at its original address in February. If it disappeared, it was done sometime after I linked to it in February.
Neither does it explain how the Where Now draft got the Buckshot data.
The Buckshot blog was done on my PC - it's way too long and complex to compose on my iPod Touch. This is in answer to your question on your first post on this thread.
I do use my iPod for simple blogs, but do not like using the slow, small screen because it's so easy to screw up. I use it for simple posts or to view my website and do simple edits of bigger posts.
