Where have you been to have only just found the Moomin family? I guess that the answer is that if you're of an age to have a four-year-old daughter then you missed out because of the generation gap that exists in the literature that children read -- or have read to them.
Wikipedia has a good entry at http://en.wikipedia.org/wiki/Moomins

OK, that's how to stop them. Now, please tell me how to stop the ones I don't want -- like my job requires me to read everything related to education, training and career guidance that comes out of government (UK) and all those quasi-government organisations. I don't however, need to have the publishers of careers guidance materials telling me about their new book or training providers saying how wonderful their new course is.
Actually I think I'm beginning to get it sussed -- since a lot of the government departments now use RSS so I can pull what I want and ditch the rest!
