When a blog becomes a book it is apparently called a Blook. Over the years this has become a bit of a trend, possibly because it is a cheap way of writing a book, there is already an established readership, and the book feeds off the blog and visa versa.
If you have a blog there are a number of websites that will self publish your musings. Some blogs get picked up by mainstream press when it has generated enough interest to warrant a book.
Recent titles that the library has bought are:
Petite Anglaise writing a blog while living in Paris with a new baby was a way for this author to alleviate the boredom and give Francophiles some enjoyment at the same time.
Craft hope : Handmade crafts for a cause This blog has encouraged readers to make handmade items for charities. This book includes many of these projects alongside where to donate.

I think the biggest ‘blog to book’ crossover hit was the cookery blog that became a book that became a film starring Meryl Streep! (“Julie and Julia: 365 Days, 524 Recipes, 1 Tiny Apartment Kitchen”).
The jury is still out for me on ‘blooks’ though: the majority at the moment seem to be lazy and/or vanity projects, but somewhere down the line they might well be at the forefront of the publishing world (cripes!).
I like your list here though, a good mix of ideas. Almost unbelievably, there is now a Twitter feed that has become a book and will soon be a sit-com on CBS in the US: “$h*! My Dad Says”. The content is definitely not suitable for everyone but it does contain some pithy one-liners – apparently genuine quotes from Justin Halpern’s dad while the pair lived reluctantly together.
This link takes you to a very funny story which reads a bit like a picture book for adults. I reckon it should qualify under the term ‘blook’. If you check the forum, you can see her other very funny stories complete with crazy but very demonstrative illustrations too.
