Problogger asks: What makes you unsubscribe from a blog’s RSS feed?

There is some interesting insight in the comments. I have tried to compile a summary of the comments so far. (I’ve stared my peeves)
17 – Too many posts
12 – Topics not focused or changes topics too often
10 – Not enough posts
10 – Not full text feeds (*)
9 – Repeated stories or unoriginal (*)
6 – Reader not interested
6 – Too long of stories or bad post layout
4 – Negative stories or attitude
4 – Too much self promotion
4 – Low quality of posts
3 – Story keep reappearing (usually frequent editing) (*)

I find it funny that not enough and too many posts were in the top three answers.
