I admit to being a bit of a geek. That must explain why in the last few minutes I did something I have not ever tried before.
I copied five pages of comments on the blog into Word.
I then found that they averaged almost exactly 2,500 words a page, but some of those were blog titles and email addresses, and so on. So I reduced that figure to 2,200 a page to allow for that.
There are 5,093 pages of comments on this blog.
That's likely to be 11.2 million words.
As a sanity check I divided that by the 102,000 total number of comments published (near enough). That's 110 words a comment, which seemed fair.
Put that 11.2 million words another way and it is at least 160 books worth of comments.
I am not looking to publish them though.
