I made it like that because its also useful to know when a new page has been directorised and analysed for back links. So to you its not useful at all to see your internal backlinks?
No, I have lots and usually I don't care about where do I link to where (as it is my linking... if I fail, it is my fault :). And from the numbers, I think there is some missing count (I have around 30 or 40 posts this year, each one pointing to at least 4 other posts in my blog, if internal are well counted that would make 160... and I have far more than 60 back links 'in the wild'!)
