1. they are self indulgent
2. who reads them bar the person who wrote them?
3. they're a bit autistic
4. they are usually as interesting as being told someone else's dream
5. you wouldn't talk in lists to your friends (assuming you had some in order to)
6. They never feature a 'to kill this week' section just to add some 'spice to them'
7. They ALWAYS feature a smug gloat that not even their mother would be pleased with them for, so why would the entire world be?

I can't think of anymore - first person who does gets to spend the Easter Holidays polishing Richard Branson's wooden teeth
